The basic principle of hydrogen fuel cells is to convert the chemical energy found in fuel into electrical energy through electrochemical reactions.The working principle of a hydrogen fuel cell involves hydrogen being broken down into electrons and hydrogen ions (protons) by a catalyst (platinum) in the fuel cell's anode. Protons pass through the Proton Exchange Membrane to the cathode, where they react with oxygen to form water and heat. The corresponding electrons flow from the anode to the cathode through an external circuit, generating electrical energy.The structure of hydrogen fuel cell stacks primarily consists of bipolar plates, membrane electrodes (proton exchange membrane coated with catalyst layer), gas diffusion layers, insulating plates, etc. Then, based on the stack, additional systems such as the air system, hydrogen system, electronic and electrical system, and water-thermal management system are integrated to form a hydrogen fuel cell power system, which is essentially a hydrogen fuel cell engine.

    Hydrogen internal combustion engines obtain power by burning hydrogen, and this type of engine, like conventional fuel engines, operates on four strokes: intake, compression, power, and exhaust, with hydrogen replacing conventional fuels.Taking the Cummins engine as an example, the structure of the hydrogen internal combustion engine is essentially similar to that of a natural gas engine, which includes components such as the cylinder block, crankshaft, cylinder head, ignition system, and mounting parts; parts of hydrogen internal combustion engines and diesel engines are also partly interchangeable, such as cylinder blocks, crankshafts, supports, flywheel housings, and other mounting components. The high degree of similarity and interchangeability of these components can utilize the economic advantages of Cummins hydrogen internal combustion engines, enhance equipment reliability, and provide crucial support in the industry's transition to low-carbon practices.

    The similarities between both require hydrogen and oxygen to participate in the reaction; All fuel storage units and hydrogen storage tanks are required; can power the vehicle. The difference is that the two generate energy in different ways, which also leads to a significant difference in efficiency, so fuel cell vehicles will have more mileage under the same hydrogen consumption; The way engines are built is also completely different; Fuel cells are more environmentally friendly than hydrogen combustion engines. In addition, there is no difference in the speed of energy release, and both internal combustion engines and fuel cells can achieve short-term high-power output.
    Compared with the two routes, the advantages of hydrogen fuel cells are high conversion efficiency, low pollution emissions, and high degree of commercial application, especially in terms of conversion efficiency, the thermal efficiency of hydrogen fuel engines is difficult to exceed 45%, while the conversion efficiency of hydrogen fuel cells can reach more than 60%.
    The advantages of hydrogen fuel engines are low cost (about 10% of fuel cells), low requirements for the purity of hydrogen, and the ability to be retrofitted with existing fuel engines. In addition, hydrogen internal combustion engines are more suitable for use in commercial vehicles such as medium- and heavy-duty trucks due to their higher output efficiency under high load conditions.

Amid the dual pressures of global energy transition and environmental protection, hydrogen energy has emerged as a clean, efficient, and renewable energy source, capturing the attention of nations and industries worldwide.

Hydrogen energy is highly regarded due to its unique advantages. First,it boasts an exceptionally high energy density. With a combustion heat value of approximately 33.3 kWh per kilogram, hydrogen far surpasses traditional gasoline and diesel. This means hat, at the same weight, hydrogen delivers significantly more energy, enhancing overall efficiency. In the transportation sector, hydrogen fuel cell vehicles (HFCVs) benefit from long driving ranges and rapid refueling, making them a viable alternative to conventional internal combustion engine vehicles and reducing reliance on fossil fuels.

​​Second, hydrogen is a clean, zero-emission energy source. When combusted, it produces only water, emitting no CO₂ or harmful pollutants, thereby contributing to carbon reduction and improved air quality. In the context of global climate change mitigation, hydrogen energy plays a crucial role in achieving carbon peak and neutrality targets.

Moreover, hydrogen is renewable. It can be produced via water electrolysis or other renewable energy sources (such as solar and wind power), enabling a sustainable energy cycle.​

Hydrogen energy has broad applications, spanning transportation, power generation, and industrial uses.

Transportation:

Hydrogen fuel cell vehicles (HFCVs) represent a major application, offering ​​Zero emissions, extended range, and fast refueling compared to traditional vehicles. Several countries have already established hydrogen production facilities and pipeline networks to support this sector.

Power Generation:

Hydrogen serves as an energy storage medium and a grid-balancing resource. Excess renewable electricity can be converted into hydrogen via electrolysis and stored; when demand rises, hydrogen can be reconverted into electricity, enhancing grid stability and renewable energy utilization.

Industrial Use:

Hydrogen is widely used in chemical synthesis, metal refining, welding, and electronics manufacturing. It also functions as a coolant and reducing agent in industrial processes. While hydrogen applications in industry are already mature, ongoing technological advancements and cost reductions are expected to expand its role further.

As hydrogen production technologies evolve, this versatile energy carrier is poised to become a cornerstone of the sustainable energy future.

The "Blowout" of Cathode-Closed Air-Cooled Stacks is Coming With the gradual expansion of low-power application scenarios such as tourist buses, forklifts, unmanned aerial vehicles (UAVs), and two-wheeled vehicles, air-cooled stacks have slowly entered the vision of mainstream fuel cell applications. Cathode-closed air-cooled stacks, with their advantages of good environmental adaptability, durability, and simple maintenance, have attracted much attention in the air-cooled fuel cell technology route and become a hot spot of pursuit. 

Technical Characteristics and Application Status of Cathode-Closed Air-Cooled Stacks

Air-cooled stacks can be divided into two categories according to their structural characteristics: cathode-open and cathode-closed. Among them, the open cathode air-cooled stack: the cathode is directly exposed to the environment, and ambient air is introduced into the stack through devices such as fans. The air serves both as a source of reaction gas and as a heat dissipation medium.

The cathode-closed air-cooled stack is characterized by the fact that the cathode is not in direct contact with the environment, and air supply and heat dissipation are carried out separately. A dedicated air supply system, such as a blower or air compressor, is usually required to provide the oxygen needed for the reaction, and an independent heat dissipation system is used to remove the heat generated during the operation of the stack.

Compared with open cathode air-cooled stacks, cathode-closed air-cooled stacks are less affected by environmental factors (such as temperature, humidity, and air quality) due to the independent air supply and heat dissipation. Moreover, they can to a certain extent avoid the adverse impact of polluted air on the service life of fuel cells, resulting in better durability and longer service life.

"The performance of cathode-closed air-cooled stacks largely depends on the design of gas channels and manifolds to uniformly distribute the supplied air," said a technical director of a domestic stack enterprise. Cathode-closed air-cooled stacks require complex air supply subsystems, which may include compressors, humidifiers, air filters, etc. This also makes them relatively less affected by surrounding environmental conditions, especially temperature and humidity. 

Of course, the advantages of cathode-closed air-cooled stacks are based on their relatively complex structure, which also leads to their relatively higher cost compared with open cathode air-cooled stacks. As Gaogong Hydrogen Power learned in the survey, as of June 2025, under the premise of bulk procurement, the price of open cathode air-cooled fuel cells is generally more than 4,000 RMB/kW, and the price of cathode-closed air-cooled systems is at least 30% higher than the former.

At this stage, cathode-closed air-cooled stacks are suitable for high-power density applications (greater than 1A/cm²). The application scenarios require sufficient space for fuel cell auxiliary systems (cooling, air supply, and pretreatment subsystems), with a typical power range between 2 kW and 100 kW.

Overall, at this stage, as the fuel cell industry gradually expands from high-power water-cooled stack systems used in commercial vehicles and passenger cars to small and medium-power air-cooled stack systems such as UAVs, forklifts, and two-wheeled vehicles, the market expansion of closed air-cooled fuel cells has just begun. Whether it can seize more market share with its own advantages remains to be seen. From the perspective of future technological development trends, future research on closed air-cooled stacks needs to focus on minimizing support systems to reduce the complexity, parasitic load, and floor space of the overall system, as well as conducting system management and control to achieve optimal performance.

Jet skis are built for thrill—fast acceleration, tight turns, and endless summer fun. But one often-overlooked component can make or break your experience: the battery. If you're still using a traditional lead-acid battery, it may be time to consider an upgrade that enhances both performance and reliability. Switching to a lithium battery can transform how your jet ski performs on and off the water.

Reduced Weight = Enhanced Agility

A key reason many riders make the switch is weight reduction. Lithium batteries are dramatically lighter than traditional ones, and that translates into a better power-to-weight ratio. The result? Faster takeoffs, smoother cornering, and more agile handling. Upgrading from older units like the YTX20-BS Motorcycle Battery to a lithium version can instantly lighten the load on your jet ski.

Dependable Starts, Every Time

Ever experienced a slow or failed start just before hitting the water? Lithium batteries deliver consistent power output and high cranking amps, even after long storage periods. Riders who choose a YTX30L-BS Battery Replacement in lithium form often report quick, confident starts—no more guessing whether the battery has enough juice.

Extended Lifespan = Lower Long-Term Costs

Although lithium batteries may come with a higher upfront price, they last far longer than standard batteries—often 2 to 4 times as long. That means fewer replacements, less hassle, and more value over time. The upgrade pays for itself in reliability and peace of mind.

Compact and Efficient

Lithium batteries don’t just weigh less—they're also more compact. This leaves more room in tight engine compartments and makes installation easier. It’s a subtle change that makes a big difference, especially for those who do their own maintenance or ride in challenging conditions.

Built for Modern Riders

Today's jet ski owners demand more: faster charging, cleaner energy, and zero maintenance. Lithium batteries deliver on all fronts. Whether you're cruising casually or racing over waves, lithium technology keeps up with your pace and performance goals.

The battery inside your jet ski might not be the flashiest part, but it's definitely one of the most important. Upgrading from a standard YTX20-BS Motorcycle Battery to a lithium-based YTX30L-BS Battery Replacement is a simple switch that unlocks a host of performance benefits. If you're ready to get the most from every ride, lithium is the way forward.

Charging and discharging batteries is a chemical reaction, but it's claimed that Li-ion is an exception.

Li-ion batteries are influenced by numerous features such as over-voltage, Undervoltage, overcharge and discharge current, thermal runaway, and cell voltage imbalance. One of the most significant factors is cell imbalance which varies each cell voltage in the battery pack over time and hence decreases battery capacity rapidly.   

How to charge ECO-WORTHY lithium battery

You can charge your lithium iron phosphate batteries whenever you want just like your cellphone. Unlike lead-acid batteries, lithium iron phosphate batteries do not get damaged if they are left in a partial state of charge, so you don’t have to stress about getting them charged immediately after use. They also don’t have a memory effect, so you don’t have to drain them completely before charging.

There are two methods for battery charging:

1. battery charger（mains power）

2. solar panel (DC power)

The most ideal way to charge a LiFePO4 battery is with a lithium iron phosphate battery charger, as it will be programmed with the appropriate voltage limits. Most lead-acid battery chargers will do the job just fine.

AGM and GEL charge profiles typically fall within the voltage limits of a lithium iron phosphate battery. Wet lead-acid battery chargers tend to have a higher voltage limit, which may cause the Battery Management System (BMS) to go into protection mode. This won’t harm the battery; however, it may cause fault codes on the charger display.

Li-ion Battery cell level and pack level control variables are needed to be maintained accurately for safe operation. These control variables are monitored and protected by the battery management system (BMS).

BMS is an electronic device that acts as a brain of a battery pack, monitors the output, and protects the battery from critical damages. This incorporates monitoring of temperature, voltage, and current, failure forecast or prevention, and data collection through communication protocol for battery parameter analysis. Battery state of charge (SOC) is the percentage of energy currently stored in the battery to the battery nominal capacity. One of the important key functions of BMS is cell balancing.

Of course, you can also use a solar panel to charge your ECO-WORTHY LiFePO4 battery, but please make sure to choose a proper controller, both PWM controller and MPPT controller are okay.

And as an SLA targeted 12V panel makes about 18V at full-sun full-load, such a 12V panel will provide more than enough voltage under all practical light conditions.

If you don't have a controller, you can connect the battery to the solar panel, too. The BMS inside will protect the battery most times.

But if there is a defect in the battery BMS, the battery will be damaged.

The ECO-WORTHY Battery Management System (BMS) performs three primary functions:

1. It protects the battery pack from being over-charged (cell voltages going too high) or over-discharged (cell voltages going too low) thereby extending the life of the battery pack. It does this by constantly monitoring every cell in the battery pack and calculating exactly how much current can safely go in (source, charge) and come out (load, discharge) of the battery pack without damaging it. These calculated current limits are then sent to the source (typically a battery charger) and load (motor controller, power inverter, etc), which are responsible for respecting these limits.

2. It calculates the State of Charge (the amount of energy remaining in the battery) by tracking how much energy goes in and out of the battery pack and by monitoring cell voltages. This value can be thought of as a fuel gauge indicating how much battery power is left in the pack.

3. It monitors the health and safety of the battery pack by constantly checking for shorts, loose connections, breakdowns in wire insulation, and weak or defective battery cells that need to be replaced.

Unless you like living on the edge, DO NOT BUY a battery without BMS!

How to choose an ECO-WORTHY lithium battery charger? Can I charge my lithium battery with a lead-acid charger?

Lithium batteries are not like lead-acid and not all battery chargers are the same. A 12V lithium battery fully charged to 100% will hold voltage around 13.3V-13.4V. Its lead-acid cousin will be approx 12.6V-12.7V.

A lithium battery at 20% capacity will hold voltage around 13V, its lead-acid cousin will be approx 11.8V at the same capacity.

So if you use the lead-acid charger to charge your lithium battery, it may not be fully charged.

You can use an AC to DC lead-acid charger powered by mains power, as charge efficiency and duration are less of a concern, it must not have automatic desulfation or equalization modes. If it does, do not use it as there is a high chance of damage to the cells or battery. This can have a significant reduction in battery longevity. If it has a simple bulk/ absorption/ float charge profile, then it can be used to recharge the battery but must be disconnected once charged and not left in trickle charge/maintenance mode. It must also have a maximum output voltage of 13V-14.5V. When it comes to DC-DC chargers and solar controllers, you must change these to LiFePO4 specific models.

Our ECO-WORTHY battery charging parameters consist of the following:

✹Bulk/absorb: 14.2V- 14.6V. ✹Float: 14.6V ✹Equalization: 13.6V- 14.0V

But it would be best for you to choose a specific lithium battery charger. We have designed our own battery charger, perfect for lithium, LiFePO4 battery charging.

This device connects directly to the battery and is meant for single-battery charging. It’s great for those with trolling motor applications or those with battery systems connected in series.

How to use the charger properly?

Most LiFePO4 chargers have different charging modes, set them like this:

battery type: LiFePO4

battery cells: 4S 

C (current): 10A (e.g. 0.3C for 30ah Battery)

Set the charger’s output current to no greater than the ‘0.7C’ rating of the battery. A recommended charging current no greater than 0.5C will help to maximize the lifespan of the LifePO4 battery.

Battery bank charging/ Separate charging

ECO-WORTHY battery has a voltage limitation on battery BMS module, which allows a maximum of 4 batteries in series connection. And no limitation for parallel.

If you charge connected batteries together, it may cause that one battery to be fully charged and the other one not, because the BMS will cut off the current when detecting one high voltage when a single one is full.

E.g. 2*30AH batteries are not full when they get to one customer, the capacity and practical voltage varied when they got disposed of in the warehouse, one is 13.2V (70%), the other is 12.9V (20%).

The customer got them wired in series, and used a suitable charger to charge them together, after a while, the display revealed full capacity status when it detected one of the batteries got the 13.6V voltage, so the charging process was accomplished, and the charger cut off the current to the pack to avoid over-charging.

But actually, the other 12.9V battery was not fully charged after the current got off, so when the customer use the battery bank, he found that the capacity did not reach his expectation, because the total output power gets limited by the low voltage one.

So we recommend you get one charging balancer. Or just charge them separately.

If you found that the battery bank's total capacity could not reach what it should be after charging the pack to full voltage, you could disconnect the batteries, and test the voltage of each, to verify if some of them did not get fully charged in the process.

Can I charge lithium batteries in the cold?

Lithium batteries rely on chemical reactions to work, and the cold can slow and even stop those reactions from occurring. Unfortunately, charging them in low temperatures is not as effective as doing so under normal weather conditions because the ions that provide the charge do not move properly in cold weather. There's one hard and fast rule: to prevent irreversible damage to the battery, don't charge them when the temperature falls below freezing (0°C or 32°F) without reducing the charge current. Because the lithium batteries suffer from a phenomenon of lithium metal plating on the anode if charged at high rates in cold temperatures. This could cause an internal short of the battery and a failure.

Please look at the following table to see the relationship between the voltage and temperature.

Can I leave the ECO-WORTHY lithium battery on charging all the time?

For a lithium battery with a low maintenance charging procedure and battery management system, it's perfectly fine and better than leaving them discharged for a long period. Regardless of whether it is a dedicated charger or a general charger, under normal conditions, it has a charging cut-off voltage, which means that it will stop charging at a certain volt. The same is true for the solar panel controller, and the controller can also be configured like this. The solar panel is directly connected for charging. If there is a problem with the BMS, it may be overcharged.

Can I recharge my lithium battery from my vehicle alternator?

Yes, but not necessarily to full charge, because most Alternators are adjusted for the lower voltage requirements of the vehicle Lead/Acid Battery (approximately 13.9V). Lithium Batteries require 14.4 to 14.6 Volts to fully charge. That being said, you can get up to approximately a 70% charge, depending on the depth of discharge and distance driven while recharging from your vehicle alternator.

It’s best to use a DC to DC charger, which helps protect and extend the life of your RV battery and not overload your vehicle alternator. Most DC to DC charger models have the same three-stage charging modes, and they will safely charge the battery and prevent alternator damage.

Golf carts are heavy, and they are meant to run for hours and miles at a time. They’re electric vehicles that can reach speeds of approximately 15, sometimes 19, or 20 miles per hour depending on the make, model, and year of the cart. They require electricity or gasoline to run. Usually, people use mains power to charge it by plugging in, and it brings an extra payment for the electricity bill. But have you thought of a solar-powered golf cart?

Can you Charge a Golf Cart with Solar Power?

A solar-powered golf cart is indeed possible. Such vehicles have been in use for several years and are gaining in popularity. They exist, and they function well. Changing the power source to solar doesn’t diminish a golf cart’s speed or performance. In addition to continued performance power, there are reasons why you should consider a solar panel golf cart.

What Golf Carts can be Powered with Solar?

Any golf cart will be powered with solar as long as its battery is solar-rechargeable.

A solar panel can charge most batteries (lead-acid, lithium-ion, and AGM), so yes, almost all golf carts can be powered with solar. And aren’t these the batteries we use in a typical solar power system? 

Why Consider a Solar Panel Golf Cart 

Benefits of a Solar Power Golf Cart

Performance

Environment

Finance

Performance Benefits

When thinking of building a solar roof on a golf cart, people usually care about the performance of solar-powered golf cart, such as:

How well a golf cart can perform when powered by the sun

Whether a solar panel kit will get enough power to maintain speed

How long does a charge last to charge the battery fully when use solar

Solar panel golf carts have as much power as traditional carts because the batteries stay the same. They aren’t slow, they stop and start with as much vigor as high-performing electric or gas carts.

The range (both driving distance and running time) of a solar-powered cart is normally better than a traditionally powered golf cart. It’s because the batteries still are charged when driving. A solar-charged cart goes up to five miles farther and has 10 percent more driving time per charge than a cart that has to be plugged for a charge.

Using solar power to charge your batteries can avoid low-speed or flameout situations caused by insufficient power while driving, and extends their life significantly. With the sun powering your golf cart, you’d no longer worry about being out on the course too long and having to deal with a dead battery

Likewise, you’d have no more hassles with a normal charger and having to watch to prevent it from overcharging.

Environment Benefits

Solar energy is clean. No carbon dioxide is released into the atmosphere as it is when batteries are plugged into the wall to charge. Similarly, no fossil fuels are consumed as they are in gas-powered golf carts.

Financial Benefits

Of course, you need to prepare a budget if you want to build a solar roof on your present golf cart. But as a long-term valid power, the solar panel usually can work for more than 20 years, consider the electricity bill it saves for you for such a long time, its ROI can be significant. 

So generally, adding solar panels to your golf cart is a brilliant idea that’ll allow you to charge it with free solar energy and run it for a long time while reducing maintenance costs significantly.

How Many Solar Panels Do You Need?

Golf cart’s battery voltage

Proper sizing of the solar panels is crucial for this project. Solar panel voltage should match the battery bank voltage for regular charging. Most golf cart batteries are 36V or 48V, this will help you know the size and number of solar panels you need. For example, the available solar panels are 12V, you’ll need 3 for a 36V and 4 for a 48 V solar golf cart battery.

A higher voltage solar panel may work with any charge controller.

The roof size of your golf cart

It may be possible to size solar panels to fit your club car’s battery, but if the roof doesn’t allow for them, you may need to reconsider.

There are generally two ways to add the panels, depending on how big your cart’s roof is:

Buy an entire solar roof panel to replace your existing plastic roof, or

Buy kits containing solar panels for golf carts to add to the roof you have

Normally, a 2-seat golf cart’s roof has space for 1 big panel, 100w if you add it on the roof, 300w if you use it to directly replace the original roof.

A 4-seats cart’s roof can handle about 4-5 pieces of 100w solar panels

How to add a Solar Panel to a Golf Cart

The golf cart solar kit should come with:

The solar panel (s)

Extension cable

Charge controller

Battery connector

Here are some simple steps to charge your cart with solar:

1. Put the solar panels on the roof of your golf cart, ensuring that it fits perfectly. Also, make sure to use an extension cable to make the panel cable reach the back of the cart.

2. Use mounting brackets or screws to tie the panel

3. Fix the charge controller on the base floor with some tapes

4. Connect the battery bank to the controller’s battery port with a suitable connector

5. Wire the solar panel extension cable to the controller’s PV port to complete the whole installation

Caution: Avoid connecting your golf cart’s battery directly to the solar panel, as doing so may put it at the risk of overcharging and possibly damage.

In addition, we've designed an MPPT step-up boost charge controller for the golf cart solar system, which can convert the 12V current from the solar panel to 48V/60V electricity to charge the 48V/60V golf cart battery bank. Reduce the panel's need and make the connection easier

Golf cart solar panel kit

Except the step-up charge controller, we now provide a whole solar kit solution, which include solar panel(s), this step-up charge controller, brackets for roof installation and necessary wires.

Concerns

Added weight

Solar roofs and weigh more than your golf cart’s original roof. It’s logical to wonder if the extra weight will slow down your cart.

Actually, compared to the total weight of a golf cart (approximately 1100 pounds), the weight of the solar panels (less than 50 pounds) isn’t enough to affect operation.

Hardness

Fortunately, PV panels are very durable and covered by tempered glass, also known as safety glass. It’s able to bear both snow and heavy rain. Unless a ball hits it at an exact right angle, otherwise, nothing will shatter or break it.

Weather condition

Solar panels charge your batteries quickly on a sunny day. While the charging time and productivity won’t be as efficient on a cloudy day as on a sunny one, charging will happen nonetheless, because what the panel needs is just daylight.
