A Proton exchange membrane fuel cell power system

摘要

A membrane electrode diffusion assembly (150) is described comprising a solid proton conducting electrolyte membrane (151) with opposite anode (153) and cathode (154) sides. Individual catalytic anode (161) and cathode (162) electrodes formed on the proton conducting electrolyte membrane are affixed in ionic contact with a non-catalytic electrically conductive diffusion layer (170) of a given porosity.
