摘要	The performance of an anode-supported solid oxide fuel cell with nanosized Ce0.8Sm0.2O1.9 (SDC) impregnated GdBaCo2O5+delta (GBCO) cathode is evaluated under various operation conditions. An SDC interlayer is applied between 8 mol% yttria-stabilized zirconia (8YSZ) electrolyte and cathode to prevent undesired chemical reaction. At 700 degrees C, the fuel cell yields a maximum power density of 790 mW cm(-2) when using simulated air as oxidant, which is promoted to 1100 mW cm(-2) in oxygen flow. The activation energies of ohmic resistance are smaller than that of bulk YSZ due to non-YSZ contribution. Electrode polarization resistance changes with fuel cell voltage while ohmic resistance nearly remains constant. The fuel cell output is mainly determined by the electrode polarization.
