Abstract
Embodiments related to fuel cells and membrane-electrode assemblies for fuel cells are disclosed. In one disclosed embodiment, a membrane-electrode assembly includes a catalyzed anode material and a membrane disposed in face-sharing contact with the catalyzed anode material. The membrane comprises mutually interpenetrating first and second phases, the first phase supporting an ionic conduction through the membrane, and the second phase supporting a dimensional structure of the membrane. The membrane-electrode assembly also includes a catalyzed cathode material disposed in face-sharing contact with the membrane, opposite the catalyzed anode material. Two opposing flow plates are also provided, each flow plate configured to distribute a reactant gas to a catalyzed electrode material of the membrane-electrode assembly. Other embodiments provide variants on the membrane-electrode assembly and methods to make the membrane-electrode assembly.
