Definition of FUEL CELL. : a device that continuously changes the chemical energy of a fuel (as hydrogen) and an oxidant directly into electrical energy.
A fuel cell produces electricity through a chemical reaction, but without combustion. It converts hydrogen and oxygen into water, and in the process also creates electricity. Itâs an electro-chemical energy conversion device that produces electricity, water, and heat. Fuel cells operates much like a battery, except they donât require electrical recharging. A battery stores all of its chemicals inside and coverts the chemicals into electricity. Once those chemicals run out, the battery dies.
