Efficiency of hydrogen fuel cell vs battery

By Ariyan Tamim : 16 October 22


The efficiency of hydrogen fuel cell vs battery is an important question to consider when looking at the potential of either technology to power vehicles. There are a number of factors that need to be considered in order to make an accurate comparison, including the type of fuel cell, the type of battery, the size of the fuel cell, and the size of the battery.

When comparing the efficiency of hydrogen fuel cells and batteries, it is important to note that fuel cells are typically more efficient than batteries. This is due to the fact that fuel cells can convert more of the chemical energy of the hydrogen fuel into usable electrical energy. In contrast, batteries typically only convert a small fraction of the chemical energy of the battery into usable electrical energy.

Now the question is which is better between hydrogen fuel cell vs battery. Though it is a very difficult question to answer don't worry. We are here to help you to determine which one is better. In this article, we will make a comparison between them and select the suitable one. So, let's get started with it.

How do Hydrogen Fuel Cells Work?

Hydrogen fuel cells are devices that use a chemical reaction between hydrogen and oxygen to create electricity. The cells are often used in electric vehicles and as backup power sources for buildings.

The process begins when hydrogen gas is fed into the anode, or negative electrode, of the fuel cell. Oxygen is fed into the cathode, or positive electrode. As the hydrogen ions flow through the electrolyte between the electrodes, they create an electrical current. The only byproduct of this reaction is water, which is why fuel cells are often touted as a clean energy technology.

Fuel cells can operate continuously as long as there is a flow of reactants. However, they typically only have a lifespan of a few thousand hours before they need to be replaced.

How do Batteries Work?

A battery is a device that converts chemical energy into electrical energy. It is made up of one or more electrochemical cells. Each cell has two electrodes, one made of a metal that can lose electrons easily (the anode) and one made of a metal that can gain electrons easily (the cathode). The anode and cathode are separated by an electrolyte. 

When the battery is not being used, the anode and cathode are stable. But when the battery is connected to a circuit, electrons flow from the anode to the cathode. This flow of electrons creates an electrical current. As the electrons flow, they create a chemical reaction that causes the anode to corrode and the cathode to be reduced. 

The battery will continue to produce electricity as long as there is a difference in potential between the anode and the cathode. When the potential difference is used up, the battery is said to be "dead."

Batteries come in many different sizes, shapes, and voltages. The most common type of battery is the lead-acid battery, which is used in cars. Other types of batteries include lithium-ion batteries, nickel-cadmium batteries, and nickel-metal-hydride batteries.

Comparison between Hydrogen Fuel Cell VS Battery- Which is Better

When it comes to powering vehicles, there are a few different fuel types that can be used. Two of the most common are hydrogen fuel cells and batteries. 

While both have their own benefits, there are also some key differences between the two. Let's discuss the efficiency of hydrogen fuel cell vs batteries and make a decision on which is better between them. Check out this comparison. 


A hydrogen fuel cell vehicle has a distinct advantage over a battery-electric vehicle in terms of weight. A battery electric vehicle typically uses a large battery pack to store electrical energy, which can add a significant amount of weight to the vehicle. 

On the other hand, a hydrogen fuel cell vehicle uses a 'fuel cell' to generate electrical energy, which is much lighter than a battery pack. As a result, a hydrogen fuel cell vehicle can be significantly lighter than a battery-electric vehicle, which gives it better performance and fuel economy.

Another advantage of a hydrogen fuel cell vehicle over a battery electric vehicle is that a hydrogen fuel cell can be refueled much faster than a battery can be charged. A battery electric vehicle typically takes several hours to charge, while a hydrogen fuel cell vehicle can be refueled in a matter of minutes. This makes a hydrogen fuel cell vehicle much more convenient to use than a battery-electric vehicle.


When it comes to distance, hydrogen fuel cells have a big advantage over batteries. Fuel cells can provide the same amount of power as a battery, but they can do it for much longer. A hydrogen fuel cell can run for about 200 miles before it needs to be refueled, while a battery will only last for about 100 miles.

This is because a battery has to store all of its energy in a chemical form, while a fuel cell can generate energy from a chemical reaction. This means that a fuel cell can keep going as long as there is fuel to feed it, while a battery will eventually run out of energy.

Fuel cells are also much lighter than batteries, so they can be used in a wider range of vehicles. This means that hydrogen fuel cells are a better option for long-distance travel, while batteries are better suited for shorter trips.

Weather Effects

Weather can affect the performance of both fuel cells and batteries. Fuel cells are less affected by cold weather than batteries. Batteries can be damaged by extreme cold or heat. Fuel cells can also be affected by extreme weather but to a lesser extent.

In general, fuel cells are more resistant to weather changes than batteries. This is because fuel cells do not rely on chemical reactions to generate electricity, while batteries do.


Infrastructure is one of the biggest differences between hydrogen fuel cells and batteries. Batteries can be charged at home or at a public charging station, but hydrogen fuel cells require a dedicated infrastructure of hydrogen refueling stations. This infrastructure is still in its early stages, which means there are far fewer hydrogen refueling stations than there are battery charging stations.

Driving Range

The big difference between hydrogen fuel cells and batteries is that fuel cells continue to produce electricity as long as they have a fuel source, while batteries store electricity that is used up over time. 

Fuel cells are more like generators than batteries, and their driving range is not limited by the amount of energy they can store. Instead, the amount of time a fuel cell can operate depends on the size of the fuel tank.

The average battery can store enough electricity to power a car for about 100 miles, while the average fuel cell can generate enough electricity to power a car for 300 miles. So, if you're looking for a car with a longer driving range, a hydrogen fuel cell vehicle is the way to go.


It is another major difference between hydrogen fuel cells and batteries. Hydrogen fuel cells are currently much more expensive than batteries, both to purchase and to maintain. This is largely due to the fact that hydrogen fuel cells are a newer technology than batteries, and the infrastructure needed to support them (e.g. hydrogen refueling stations) is still in development.

However, costs are expected to come down as hydrogen fuel cell technology improves and becomes more widely adopted. In the meantime, batteries are a more affordable option for those looking to switch to an electric vehicle.

Efficiency of Hydrogen Fuel Cell VS Battery- The Winner

The race to find the best alternative fuel source has been ongoing for many years now. The two front-runners in this race are hydrogen fuel cells and batteries. So, which one is the better option?

To answer this question, we must need to know the comparison between them and we already made that in this article. first, understand how each technology works. 

All things in consideration we can say that the hydrogen fuel cell is far ahead of the battery and is the clear winner. But for those looking for something good at a low price, batteries can be an ideal option.

Final Thought

The efficiency of hydrogen fuel cells vs batteries is a matter of debate. Some experts believe that hydrogen fuel cells are more efficient than batteries, while others believe that the opposite is true. 

The truth is likely somewhere in the middle, and the most efficient way to power a car may vary depending on the specific circumstances.

In this article, we try to make a comparison between them and select which one is better to choose. If you have any other questions required; then feel free to comment on us. We will try to answer you. Thank you all.
