An interconnect in an anode-supported flat-tubular solid oxide fuel cell (SOFC) electrically connects unit cells and separates fuel and oxidant gases in a stack. An anode-supported flat-tubular SOFC with a highly conductive and dense interconnect film is developed. The dense interconnect film having an n-type conducting layer on the reducing side and a p-type conducting layer on the oxidizing side is fabricated on a porous anode support by a simple and cost-effective screen-printing process, followed by co-sintering with the anode and the electrolyte. The interconnect exhibits low resistance and high stability in a dual atmosphere. The anode-supported flat-tubular cell with the ceramic interconnect shows a power density as high as 360 mW cm(-2) at 850 degrees C.
