Abstract
Disclosed is a sandwich-type solid polymer electrolyte fuel cell comprising in sequence, a cathode current collector; a cathode electrically connected to the cathode current collector, said cathode containing an ion exchange resin and cathode catalyst particles in electrical communication with the cathode; an ion exchange membrane; an anode containing an ion exchange resin and anode catalyst particles in electrical communication with the anode; and an anode current collector electrically connected to the anode. The cathode and/or anode contain, in the ion exchange resin, catalyst metals capable of promoting the reaction of hydrogen and oxygen gases to produce water. The catalyst metals are insulated electrically from the current collectors due to the presence of the ion exchange resin which has no electrical conductivity.
