Patent ID: 8530114

Claim:
A method of fabricating an interconnect for a solid oxide fuel cell (SOFC), comprising: melting a charge comprising copper and from 20 to 38 volume percent molybdenum and then cooling the melted charge to form an ingot comprising a metallic composite having a copper matrix and spheroids comprising molybdenum dispersed within the matrix; forging the ingot followed by a first anneal to form a rough bar of metallic composite; swaging the rough bar followed by a second anneal to form a plurality of rods suitable for drawing; drawing the plurality of rods followed by a third anneal to form a plurality of wires of the metallic composite; and bundling and canning the plurality of wires to form a sheet of the metallic composite, wherein the sheet comprises a plurality of discontinuous, elongated, substantially uniaxial reinforcement fibers formed from the spheroids, and wherein the sheet is suitable for use as an interconnect in an SOFC.
