8.5 Parts of an Ethanol Fuel Cell
Ethanol fuel cells are also similar to hydrogen fuel cells in their design. They both have an anode and cathode separated by an electrolyte, which allows protons to pass from one side to the other. They both use a platinum catalyst to help oxidize the fuel. And they both need wires to carry the electric current from the anode, through an electric motor, to the cathode.
