Abstract: A fuel cell array comprising a plurality of serially connected fuel cell units. A respective fuel cell unit comprises a fuel cell and a tubular cap capped on each end of the fuel cell. The fuel cell unit further comprises an electrically conductive terminal layer forming an outermost laminate of the fuel cell in one end of the fuel cell and extending in the longitudinal direction from the one end of the fuel cell toward the other end thereof to terminate past a tubular skirt of the tubular cap to form a connection area. The terminal layer is directly laminated on the fuel electrode layer in a fuel electrode layer exposition area and directly laminated on the solid electrolyte layer in a solid electrolyte layer exposition area. The fuel cell unit further comprises a grass material forming a sealing layer circumferentially around the fuel cell to fill between the inner surface of the tubular cap and the outer surface of the fuel cell.

Abstract: Disclosed is a durable solid oxide fuel cell that is less likely to have a problem of a conventional solid oxide fuel cell that an air electrode containing a peroviskite oxide, when exposed to a reducing atmosphere, is separated at the stop of operation, especially shutdown. The solid oxide fuel cell includes an air electrode that is obtained by firing a compact containing a perovskite oxide and sulfur element. The content of the sulfur element in the air electrode as fresh after firing or before the start of power generation is in the range of 50 ppm to 3,000 ppm. The separation of the air electrode is effectively suppressed at the shutdown operation.
