Abstract
An electrode includes a proton conducting electrolyte phase, an electronic conducting phase, and a metal or metal alloy catalyst in contact with each of the phases. The electronic conducting phase is infiltrated with the proton conducting electrolyte phase such that the phases form a solid nanocomposite with bulk electronic conductivity.
Claims19
An electrode comprising:
- a proton conducting electrolyte phase;
- an electronic conducting phase having pores thereon and interior diameter regions therein both infiltrated with the proton conducting electrolyte phase such that the phases form a solid nanocomposite with bulk electronic conductivity;
- and
- a metal or metal alloy catalyst in contact with each of the phases.
