How To Make a Hydrogen Fuel Cell For a Car? 

Hydrogen fuel cells offer sustainable energy solutions with zero-emission energy conversion, making them attractive choices for eco-conscious drivers seeking to decrease their carbon footprint. But how exactly can one create one in their car?

Understanding Hydrogen Fuel Cells

Hydrogen fuel cells create electricity by combining hydrogen and oxygen in a chemical reaction. They consist of an anode, cathode, and electrolyte membrane; hydrogen gas (H2) enters through the anode while air oxygen (O2) feeds directly to the cathode; H2 molecules break apart into protons and electrons which travel independently towards each electrode, creating an electric current to power your car’s electric motor.

Steps to Create a Basic Hydrogen Fuel Cell

Here is a simplified guide to building a primary hydrogen fuel cell, primarily for educational purposes. Please note that making a practical, car-ready fuel cell is a complex process requiring advanced engineering knowledge and resources.

Materials required:

  • Two platinum-coated electrodes
  • A proton exchange membrane (PEM)
  • Two conducting plates
  • A hydrogen source
  • Wires
  • An electric load (like a small light bulb)
  1. Assemble the Fuel Cell: Place the PEM between the two electrodes. This sandwich-like arrangement forms the core of your fuel cell.
  2. Install the Conducting Plates: Place the conducting plates on either side of the electrodes. Connect one container to the positive terminal and the other to the negative terminal of your electric load.
  3. Introduce Hydrogen: Feed hydrogen gas to the anode (connected to the positive terminal). This can be done by attaching a tube from a hydrogen gas cylinder to the plate covering the anode.
  4. Start the Reaction: Once the hydrogen is introduced, it will split into protons and electrons at the anode. The protons will pass through the PEM while the electrons travel through the circuit to power the load, eventually reaching the cathode.
  5. Combine Hydrogen and Oxygen: At the cathode, the electrons and protons combine with oxygen from the air to form water, the only by-product of this reaction.

Making a Practical Hydrogen Fuel Cell Car

Building a hydrogen fuel cell suitable for powering a car is a complex and time-consuming task best left to professionals, given the high pressures and temperatures involved. Furthermore, designing a vehicle capable of accommodating and operating it also plays an integral role.

Companies worldwide are investing heavily in research and development of this technology, leading to an increasing number of hydrogen fuel cell vehicles (FCVs) hitting roads worldwide, moving us one step closer to a zero-emission future.

What are The Advantages of Hydrogen Fuel Cells?

Hydrogen fuel cell technology presents several advantages over other power sources, including: 

Renewable and Readily Available

Hydrogen is one of the most abundant elements in our universe and, despite challenges associated with its extraction from water, offers a tremendous and renewable source of energy that could meet our future zero-carbon combined heat and power supplies.

Hydrogen is a Clean and Flexible Energy Source to support Zero-Carbon Energy Strategies

Hydrogen fuel cells offer an inherently clean energy source with no adverse environmental impacts during operation – byproducts are simply heat and water. Furthermore, unlike biofuel or hydropower production processes that require large plots of land for production purposes, hydrogen production doesn’t infringe upon nearby environments like it does when producing biofuel or hydropower. NASA have been exploring hydrogen as a resource, with any byproduct water used as drinking water for astronauts. Hydrogen fuel cells offer a non-toxic fuel source and thus surpass coal, natural gas, and nuclear power, which all have potential health hazards or are difficult to access. Hydrogen production, storage, and use will be essential in driving further renewable energy growth by matching their intermittent supply modalities with end-user demands while eliminating costly grid infrastructure upgrades.

More Powerful and Energy Efficient than Fossil Fuels

Hydrogen fuel cell technology offers a highly dense energy source with excellent energy efficiency. Hydrogen has one of the highest energy content among standard fuels by weight; high-pressure gaseous and liquid hydrogen have around three times greater gravimetric energy density (around 120MJ/kg) compared with diesel and LNG, as well as similar volumetric energy density to natural gas.

Highly Efficient when Compared to Other Energy Sources

Hydrogen fuel cells are more energy efficient than many traditional and renewable energy solutions, including many green solutions. Their efficiency allows for the creation of more energy per pound of fuel consumed; for instance, conventional combustion power plants only operate at 33-35% efficiency, while hydrogen fuel cells can achieve up to 65% compared with 33-35% efficiency for conventional power plants; similar efficiency exists when powering vehicles: hydrogen fuel cells use 40-60% more of its energy while simultaneously cutting consumption by 50%!

Almost Zero Emissions

Hydrogen fuel cells do not emit greenhouse gas emissions like other sources, thus decreasing pollution and improving air quality.

Reduces Carbon Footprints

Hydrogen fuel cells emit no greenhouse gases during operation and thus have no carbon footprint during use.

Fast Charging Times

Hydrogen fuel cell power units charge at a very rapid pace, similar to that seen with traditional internal combustion engine (ICE) vehicles, and far quicker than battery-powered electric cars. While battery-powered electrics require 30 minutes or more per charge cycle, hydrogen fuel cells recharge in under five minutes allowing hydrogen-powered vehicles to offer the same flexibility as traditional cars.

No Noise Pollution

Hydrogen fuel cells do not pollute noise like other renewable energy sources, such as wind power. As with electric cars, hydrogen-powered vehicles tend to be much quieter than those powered by conventional internal combustion engines.

No Visual Pollution

Hydrogen fuel cells do not have the exact space requirements, meaning less visual pollution and increased visibility.

Long Usage Times

Hydrogen fuel cells offer greater efficiency in usage times, providing a similar range to fossil-fueled vehicles (around 300 miles). This outshines electric vehicles (EVs), many of which now incorporate fuel cell power units as “range extenders”. Furthermore, hydrogen fuel cells do not significantly deteriorate with cold weather as their electric counterparts do, and this advantage becomes even more significant when coupled with quick charging times.

Optimizing Efficiency and Performance of Hydrogen Fuel Cell For Car

As we seek a greener future, hydrogen fuel cells have emerged as a promising technology to power vehicles with minimal environmental impact. Optimizing their performance and efficiency is essential to reach their full potential – we will examine strategies for increasing both the performance and efficiency of hydrogen fuel cell vehicles.

Understanding Fuel Cell Efficiency

Hydrogen fuel cells operate by converting hydrogen’s chemical energy into electricity, with efficiency measured by how effectively they convert that hydrogen energy to usable power. Many factors can impact this, including the design of the cell itself, the purity of its hydrogen supply, and the operational conditions for which the cell operates.

Tips for Optimizing Fuel Cell Efficiency and Performance

  1. Maintain Optimal Operating Conditions: Fuel cells perform best under specific temperature and pressure conditions. Ensure your fuel cell operates within these parameters for optimal efficiency.
  2. Ensure High-Quality Hydrogen Supply: The purity of the hydrogen fuel can significantly impact the performance of your fuel cell. Impure hydrogen can lead to contamination, reducing the effectiveness of the fuel cell.
  3. Proper Hydration of the Fuel Cell: The proton exchange membrane (PEM) in the fuel cell needs to be properly hydrated to function efficiently. Inadequate hydration can lead to lower efficiency and potentially damage the fuel cell.
  4. Regular Maintenance: Just like any other part of a vehicle, regular check-ups and maintenance of a fuel cell system are essential. This can prevent minor issues from escalating into more significant problems that could affect efficiency and performance.
  5. Optimize Energy Management: A well-designed energy management system can improve overall vehicle efficiency. It involves optimal control of fuel cell output, battery charging/discharging, and power distribution.

The Future of Fuel Cell Efficiency

Researchers worldwide are constantly investigating ways to enhance the performance and efficiency of hydrogen fuel cells. Design, materials, and system integration advancements are creating more energy-efficient vehicles using hydrogen power.

Recent advances in nanotechnology, advanced materials, and electrochemistry promise to significantly increase fuel cell efficiency. Researchers are exploring using new catalyst materials, which may enhance fuel cell reactions more efficiently while decreasing platinum requirements and costs, thus decreasing the overall costs of fuel cells.

Testing and Troubleshooting

As automotive technology strives towards more eco-friendly transport options, hydrogen fuel cell vehicles (FCVs) have emerged as exciting zero-emission options. While these groundbreaking cars hold great promise, proper understanding and testing of an FCV system are critical to ensure optimal performance and safety.

Testing a Hydrogen Fuel Cell

  1. Visual Inspection: Start with a basic visual check. Look for any obvious issues, such as leaks, cracks, or loose connections that may impact the cell’s operation.
  2. Voltage and Current Tests: Utilizing a multimeter, check the voltage output across the fuel cell. A functioning fuel cell should produce a voltage consistent with its design specifications when hydrogen and oxygen are supplied.
  3. Performance Testing: Test the cell under load, monitoring its performance. Check for any voltage or power output drop that may indicate internal issues.

Troubleshooting a Hydrogen Fuel Cell

If your fuel cell isn’t performing optimally, here are some potential issues and solutions:

  1. Low Voltage Output: If the fuel cell’s output is lower than expected, it could indicate a shortage of fuel (hydrogen), blockage in the gas channels, or a fault in the membrane.
  2. Leaks: If you notice water or gas leaks, it could be due to a damaged or improperly sealed fuel cell. Leaks should be addressed immediately to prevent damage to the cell and potential safety hazards.
  3. Decreased Performance Over Time: If the fuel cell’s performance diminishes over time, it could be due to contamination or degradation of the PEM or electrodes.
  4. Overheating: Overheating can cause severe damage to the fuel cell. It could be due to overloading or inadequate cooling mechanisms.
  5. Bad Power: If your vehicle is underperforming, it could be due to a malfunctioning fuel cell stack or a problem with the hydrogen supply.

Navigating Hydrogen Fuel Cell Maintenance

Maintenance of hydrogen fuel cell systems requires specific knowledge and training due to high-pressure hydrogen use and its complexity. Certified professionals should conduct any repairs or maintenance for best results; regular checks as per manufacturer guidelines will help ensure your FCV remains in excellent working order.


Why can’t we use hydrogen as a fuel for cars?

The vast majority of car companies have turned away from hydrogen because of the high density of energy consumed in its production, as well as poor funding and backing from governments, which is stopping the hydrogen revolution from expanding ever more.

How much hydrogen do you need to run a car?

The amount of hydrogen required is determined by the size of the engine. 0.15 Litres/minute per 1L of engine size is ideal.

How many kg of hydrogen in a car?

Cars carry around 5 or 6 kg of hydrogen in highly pressurized tanks. The car’s autonomy is, therefore, around 400 miles. The use of a hydrogen-powered car does not mean a change in daily habits since it takes no more time to fill up than with a normal car, just 3 to 5 minutes.

What is the mileage of 1 kg of hydrogen?

FCEBs have an average fuel economy of approximately 7.9 miles per kilogram of hydrogen, which equates to approximately 7 miles per diesel gallon equivalent (DGE).
