Question

describe hydrogen oxygen H2O2 of fuel cell​

Answer 1

Explanation:

A fuel cell is a device that converts chemical potential energy (energy stored in molecular bonds) into electrical energy. A PEM (Proton Exchange Membrane) cell uses hydrogen gas (H2) and oxygen gas (O2) as fuel. The products of the reaction in the cell are water, electricity, and heat.

Answer 2

A hydrogen–oxygen fuel cell is a non–polluting clean fuel since the only combustion product is water. Fuel cells do not produce pollutants like carbon monoxide, sulfur dioxide and nitrogen oxides - gases you get from fossil fuel combustion in power stations or burnt road vehicles.
