Abstract:
1. A solid oxide fuel cell for electrochemically reacting a fuel gas with an oxidant gas to produce a DC output voltage, said solid oxide fuel cell comprising: a layer of ceramic ion conducting electrolyte defining first and second opposing surfaces; a conductive anode layer positioned at the first surface of said electrolyte layer; and a conductive cathode layer positioned at the second surface of said electrolyte layer; wherein said electrolyte layer is disposed between said anode layer and said cathode layer; wherein said conductive cathode layer consists essentially of a copper-substituted ferrite perovskite material and the copper-substituted ferrite perovskite material is in contact with said electrolyte layer; wherein said solid oxide fuel cell is operable at temperatures less than about 750° C.
