Abstract
A process for producing metal oxide dispersion-strengthened anodes for use in fuel cells in which a metal alloy powder comprising at least one metal powder and at least one metal oxide forming phase is formed into a 'green' cohesive structure. The 'green' cohesive structure is heated in a sintering furnace resulting in simultaneous sintering and internal oxidizing of the oxide forming phase within the 'green' cohesive structure, forming an oxide dispersion-strengthened structure. To promote simultaneous sintering of the 'green' cohesive structure and internal oxidation of the oxide forming phase within the 'green' cohesive structure, an oxidizing agent is disposed within the 'green' cohesive structure or is applied to the exterior of the cohesive structure.
