What Are Hydrogen Fuel Cell Cars?

Hydrogen Fuel Cell Cars

Hydrogen fuel cell cars are significant cars that use hydrogen as fuel as their motive energy, and as much making them energy-efficient substitutes compared to gasoline vehicles.

Additionally, hydrogen fuel cell vehicles (FCVs) utilize pressurized hydrogen to create electricity from a REDOX reaction of hydrogen and atmospheric oxygen. Although, this generated electricity is distributed partially to a battery pack used when the FCVs are functional.

How Does A Hydrogen Fuel Cell Work?

Without much ado, I would dive into the chemistry of the hydrogen fuel cell as quickly as!

However, a hydrogen fuel cell; results from a REDOX reaction between these common elements, hydrogen, and oxygen.

Although this reaction converts helpful energy into electricity, hydrogen becomes the fuel. It combines with oxygen in the atmospheric air to produce an electrochemical cell, having the products as electricity and water vapor.

Similarly, this REDOX reaction occurs through a multi-step procedure involving the cathode, anode, and electrolyte membrane. However, the hydrogen molecules split at the negatively-charged anode into protons and electrons.

Thus, the electrons create electricity and heat as they are in the circuit. In like manner, the protons join the electrolyte membrane. Then, the combination of electrons, oxygen, and protons forms water molecules at the cathode.

So far, flow plates facilitate the transfer of ions between the anode and the cathode. Hence, fuel stacks are required to increase the quantity of generated electricity since a cell can only produce less than 1.16 volts.

How Do Hydrogen Fuel Cells Work In Cars?

The working mechanism of the hydrogen fuel cells in cars is below.

Interestingly, the fuel cells’ powering is possible by compressed hydrogen gas inside the onboard fuel cell stack, which converts the fuel’s chemical energy to electrical energy without burning the gas. The generated electricity powers the vehicle’s electric motor.

The above process would give the car’s tailpipe zero emissions and water as the only by-product. In a general perspective, the process, as mentioned earlier, and the mechanism apply to;

How does a car engine run on hydrogen?

Can A Car Engine Run On Hydrogen?

Of course, yes, Vehicles run on hydrogen! Apart from the FCVs, you can modify other vehicle engines to run or operate on 100% hydrogen since they are far more efficient. Isn’t this awesome? Perchance, science and technology have made things easy and more fascinating.

Toyota is selling hydrogen cars in selected locations, indicating that car engines can run on hydrogen so that you can get one, any case!
