Abstract
Methods of fabricating anodes for high temperature fuel cell in which an alloy powder with a major phase of a base metal and a minor phase of a stabilizing, alloying metal is preformed into the shape wanted in the anode. This green structure is sintered under conditions which produce a metallic, essentially oxygen-free structure. The sintered structure is selectively oxidized in situ in a fuel cell under conditions which promote internal oxidation and a consequent increase in the stability of the anode under operating conditions where the anode is exposed to high temperatures for long periods of time.
