Hydrogen Fuel produces electricity from the stroke of oxygen from air and water. A straight combustion engine making use of oxygen & fossil fuel is burned or else oxidized that produces heat & mechanical motion. Fuel cell as well uses oxidization to make the electricity. When it is powered by hydrogen only by-product is heat & water. Fuel cell is made of thin flat cells covered together producing electricity.
