Patent ID: 7468218

Claim:
An electrode in a solid oxide fuel cell comprising a two-phase mixture having: a first phase of doped strontium titanate of the general formula Sr 1-x M x TiO 3-δ , where M is selected from a group consisting of yttrium, scandium, lanthanum, and combinations thereof, wherein x may vary typically from 0.01 to 0.5, and wherein δ is indicative of some degree of oxygen non-stoichiometry; and a second phase of donor-doped cerium oxide of the general formula N y Ce 1-y O 2-δ , where N is niobium (Nb), vanadium (V), antimony (Sb) tantalum (Ta), or combinations thereof, and where “y” may vary typically from 0.001 to 0.1; and wherein the electrode is an oxide substantially without a metal phase and the ratio of Ti in said first phase to the sum of Ce and N in said second phase is from about 0.2 to about 0.75.
