Abstract: A method of manufacturing an electrically conductive interconnect for a solid oxide fuel cell stack, including the steps of (a) making a metal substrate having a first surface configured for electrical contact with an anode of the solid oxide fuel cell stack and a second surface configured for electrical contact with a cathode of the solid oxide fuel cell stack; (b) depositing a layer comprising metallic cobalt over at least a portion of at least one of the first and second surfaces; and (c) subjecting the metallic cobalt to reducing conditions, thereby causing at least a portion of the metallic cobalt to diffuse into the metal substrate.

Abstract: A solid oxide fuel cell stack that contains a plurality of fuel cells, each of which includes an anode and a cathode disposed on opposite sides of a solid electrolyte, and an electrically conductive interconnect disposed between the anode and cathode. The interconnect includes a substrate and a first surface in electrical contact with the anode and a second surface in electrical contact with the cathode, wherein at least a portion of at least one of the surfaces includes cobalt.
