    Abstract:

    In this paper,the porous YSZ film was prepared by aqueous tape casting and the YSZ electrolyte film was prepared by organic tape casting. The porous YSZ-compact YSZ film composite was prepared via the stack pressure co-firing of the porous YSZ film and YSZ electrolyte film. The impregnated anode SOFC single cell was prepared by chemical impregnation method with the solution of ferricSnitrateS、cobalt nitrate and nickel nitrate was impregnated in porous YSZ layer of the composite matrix. The performance of iron-based anode catalysts was studied,the electrical properties of different anode SOFC single cell at different temperature were tested and the morphology of the anode was observed by SEM. The anti-carbon performance of Co-YSZ and Ni-YSZ anode single cell was tested and compared. Experimental results show the catalytic activity of cobalt in the hydrogen atmosphere was the highest,the nickel is the second,and the iron is the worst. The catalytic activity of cobalt in alcohol atmosphere was still better than that of nickel, and the anti-carbon performance of Co-YSZ anode single cell was better than that of Ni-YSZ single cell. The catalytic activity and the anti-carbon performance of cobalt in Iron-based catalyst were best.
