摘　　要：设计并制备了Ni-Fe金属支撑型第三代固体氧化物燃料电池(SOFC)并对其进行表征.SOFC电池阳极、电解质、阴极分别采用了NiO-YSZ(氧化钇稳定的氧化锆)、YSZ及YSZ-LSCF(La_(0.6)Sr_(0.4)Co_(0.2)Fe_(0.8)O_(3-δ))材料,制备方法采用了单层流延及多层等静压结合的方法.在650~750℃的温度范围内对电池的性能进行表征,当阴极为空气,阳极通入氢气时,电池750℃最大功率密度为0.74 W/cm^2,电阻为0.45Ωcm^2,测试结果表明,此结构为Ni-Fe//Ni-YSZ//YSZ//YSZ-LSCF的金属支撑型固体氧化物燃料电池具有极高的性能及实用价值.A third generation Ni-Fe supported solid oxide fuel cell( SOFC) was designed and fabricated in this paper. The anode,electrolyte and cathode materials used in the cell were NiO-YSZ,YSZ,and YSZ-LSCF( La_(0. 6)Sr_(0. 4)Co_(0. 2)Fe_(0. 8)O_(3-δ)). The preparation method is single-layer casting combined multi-layer isostatic pressing method. Tested the cell at 750 ℃ 、700 ℃ and 650 ℃,using H_2 at anode side and air at cathode side,as a result,the maximum power density and the resistance of the cell were 0. 74 W·cm^(-2) and 0. 45 Ω·cm^2,at 750 ℃. Metal supported cells with a configuration of Ni-Fe//Ni-YSZ//YSZ//YSZ-LSCF were successfully fabricated and characterized,and it showed promising application prospects.
