N2 - (La0.75Sr0.25)0.95MnO 3±δ(LSM), (La0.6Sr0.4) 0.9Co0.2Fe0.8O3-δ(LSCF), La0.6Sr0.4CoO3-δ(LSC), Ce 0.9Gd0.1O1.95(CGO) nano-powders and LSM+YSZ, LSCF+CGO, LSC+CGO composite cathodes have been researched, and reported in this paper. Microstructure characterizations and electrical properties measurements showed resultant powders to be of high purity, single phase, with slight aggregation with grain size less than 100 nm and high performances. Excellent polarization resistance of 0.18 Ω.cm2 at 750°C, 0.12 Ω.cm2 at 700°C, and 0.12 Ω.cm2 at 650°C were obtained respectively in the LSM+YSZ/YSZ/LSM+YSZ, LSCF+CGO/CGO/LSCF+CGO and LSC/CGO/YSZ/CGO/LSC symmetric cells. Anode supported cells with configuration of Ni+YSZ/YSZ/LSM+YSZ, Ni+YSZ/YSZ/CGO/LSCF+CGO and Ni+YSZ/YSZ/CGO/LSC+CGO exhibited maximum power densities of 0.63 W/cm 2 at 750°C, 0.54 W/cm° at 700°C and 0.42 W/cm2 at 650°C (H2/air, active electrode area of 4x4 cm2), respectively. These results indicated that the YSZ-based anode supported cells with LSM-YSZ, LSCF-CGO, LSC-CGO composite cathodes have the feasibility to be operated at 750-650°C with an acceptable power density.
