A redox cathode system of an electrical conductor immersed in an acidic solution containing cupric chloride and excess chloride ions is disclosed for use in fuel cells. The system is isolated from the anode system by an ion-exchange membrane; and an anode having catalytic material associated therewith and an acid anolyte are employed. An organic hydrogen-containing fuel, e.g. formaldehyde, and an oxygen-containing oxidant, e.g. air and hydrogen peroxide, are preferred. |
