A site deficient (La0.8Sr0.2)0.95MnO3 (LSM95) powder was synthesized by solid state reaction as a cathode material. The commercial Zr0.9Sc0.1SO1.95 (SSZ) was selected as an electrolyte material and La0.8Sr0.2Cr0.5Mn0.5O3- (LSCrM) was synthesized by sol-gel method as an anode material. Accordingly, single cells of LSCrM-CeO2|SSZ|3YSZ-LSM95 were prepared by tape casting, sintering and impregnation. The single cell test results for LSCrM-CeO2|SSZ|3YSZ-LSM95 with 0.11 g·cm -2 CeO2 and using CH4 as a fuel showed the power densities of 1.68, 4.70, 12.4, 28.08 and 54.78 mW·cm -2 at 600, 650, 700, 750 and 800 oC, respectively. Durability test at the current density of 46.50 mA·cm -2 for over 130 h revealed that the cell degradation was owing to the decrease of open circuit voltage. The impregnated anode had good stability in performance. No carbon deposition was observed on the anode after the cell operation with CH4. The as-synthesized LSM95 powder exhibited good chemical compatibility with zirconia electrolyte, making it possible to prepare cathode supported cells with co-sintering. Meanwhile, LSCrM could form the perovskite phase at 900 oC and obtain the similar thermal expansion coefficient to the cathode support and electrolyte, which is contributed to the stability of multi-layer structure in the cell. The successful preparation of the cathode supported cells with a simple method shall provide a good platform for the research of various new anode materials. With further optimization in the porosity of cathode support and introduction of more active cathode functional layer, the cell performance will be enhanced.
