摘　　要：用浆料旋涂法在NiO-YSZ(氧化钇稳定的氧化锆)阳极支撑体上制备了一层11.5μm厚的致密YSZ薄膜。在薄膜上制备了Sm0.2Ce0.8O1.9(SDC)浸渍的La0.7Sr0.3MnO3(LSM)复合阴极。以氢气为燃料,阴极暴露在静态空气中,单电池在700、750、800℃的最大比功率分别为691、898、1118mW/cm2。当阴极通入50mL/min的氧气时,单电池在800℃的最大比功率比空气气氛下的性能高出84%,达到2057mW/cm2,在中温区达到优异的性能。Dense 11.5 μm thickness 8 % Y2O3-stabilized ZrO2 （YSZ） electrolyte films were deposited on NiO-YSZ anode substrate by slurry spin coating method. Sm0.2Ce0.8O1.9 （SDC）-impregnated La0.7Sr0.3MnO3 （LSM） composite cathodes were prepared on the YSZ films. A single fuel cell was tested with hydrogen as the fuel and the cathode was exposed to the stationary air. The maximum power densities of the cell were 691,898 mW/cm^2 and 1 118 mW/cm^2 at 700,750 ℃ and 800 ℃, respectively. When 50 mL/min oxygen was introduced to the cathode, the maximum power density of the cell was increased to 2 057 mW/cm^2 at 800 ℃, which was improved about 84% compared to that of the cell with the cathode exposed to the stationary air,and reached excellent performance at intermediate temperature.
