What Is Hydrogen Fuel Cell 

A fuel cell is a means of generating electricity by a chemical process. The positive (cathode) and negative anode are the two electrodes of the fuel cell. Chemical processes take place in these electrodes. It differs from a dry cell because the fuel is supplied from the outside, and the fuel is not contained inside the cell. 

As long as the fuel cell is supplied with hydrogen and oxygen, it continues to generate electricity. Every cell has an electrolyte. It moves electrically charged particles from one electrode to another. Catalysts are also included to accelerate the chemical reactions at the electrodes. This fuel cell also generates a small amount of direct current (DC). 

A fuel cell electric vehicle is a device that produces electricity by an electrochemical process using hydrogen as a fuel source and an oxidizer. The fuel cell combines hydrogen and oxygen to produce an electric current and water is a byproduct in the process.

How does a Hydrogen Fuel Cell work 

Hydrogen molecules enter the fuel cell through the anode. Here electrons are removed from hydrogen molecules by a chemical process. The electroless molecules are called hydrogen ions (H+). 

Hydrogen ions (H+) move through the electrolyte inside the fuel cell towards the cathode carrying an electric charge. Electrons are negatively charged. The electrons removed by the hydrogen molecules at the anode pass through the electrical wires to the exit of the fuel cell. 

Power wires connect the cathode on the outside of the fuel cell to the anode via the ‘load’. ‘Load’ is a work which has to be done by electricity, like fan, lute, motor etc. 

 

 

Fuel Cell Is Useful 

Unlike conventional combustion based technology, they emit very little greenhouse gases and the air emitted by them does not cause any harm to health. The hydrogen used in fuel cells produces water as a by-product and is more efficient than conventional combustion engines. 

Unlike other battery-powered vehicles, FCEVs do not require a charging point, but will be fueled with hydrogen as fuel and can cover a distance of 300 km once the tank is full.
