Patent ID: 8691467

Claim:
An interconnect for a solid oxide fuel cell, the interconnect comprising: a high-temperature aluminum-containing surface-alumina-forming steel structure; a second structure to which the high-temperature aluminum-containing surface-alumina-forming steel structure is electrically connected; and a brazed gas-tight seal comprising an active braze filler material formed between and in direct contact with each of the high-temperature aluminum-containing surface-alumina-forming steel structure and the second structure, wherein the active braze filler material comprises a clad-laminated alloy wherein the clad-laminated alloy consists of a sandwich of nickel foil between two titanium foils, and the high-temperature aluminum-containing surface-alumina-forming steel structure is a metal frame, the second structure is a current collector or bus bar positioned on an electrolyte sheet and any alumina layer has been removed from a surface portion of the steel structure where an electrical contact is to be formed.
