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)
- Assemble the Fuel Cell: Place the PEM between the two electrodes. This sandwich-like arrangement forms the core of your fuel cell.
- 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.
- 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.
- 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.
- 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.

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.
