Abstract:
1. An integral solid oxide fuel cell for electrochemically reacting a fuel gas with an oxidant gas at an elevated temperature 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 in contact with the first surface of said electrolyte layer; and a conductive cathode layer in contact with the second surface of said electrolyte layer; wherein said electrolyte layer is disposed between said anode layer and said cathode layer; wherein said conductive anode layer comprises a cerium-modified doped strontium titanate material; wherein the cerium-modified doped strontium titanate material comprises an A-site dopant selected from the group consisting of lanthanum, scandium, yttrium and combinations thereof; and wherein cerium is present in the cerium-modified doped strontium titanate material in an amount of at least about 2 atomic percent.
