Abstract

A solid oxide fuel cell (SOFC) stack includes a plurality of SOFCs, and a plurality of interconnects, each interconnect containing a conductive perovskite layer on an air side of the interconnect. The stack in internally manifolded for fuel and the conductive perovskite layer on each interconnect is not exposed in the fuel inlet riser. The SOFC electrolyte has a smaller roughness in regions adjacent to the fuel inlet and fuel outlet openings in the electrolyte than under the cathode or anode electrodes.
