摘要 研究了阳极支撑一体化电池Y_2O_3稳定ZrO_2(YSZ)基体孔隙率对电导率和力学性能的影响,分析了不同孔隙率下YSZ基体的孔结构,优化出最佳孔隙率(65.8%)的YSZ基体。在此基础上,通过浸渍工艺制备了标准尺寸阳极支撑一体化SOFC。测试结果表明,750℃最大功率密度达0.35 W/cm^2。 The conductivity and bending strength of Y203 stabilized ZrO2 （YSZ） ceramic substrates with different porosities were investigated. The pore structure of YSZ with different porosities was analyzed, and the optimized porosity of 65.8% was obtained. Anode supported tri-layer single cell with the standard size was fabricated via impregnation technique. The results show that the maximum power density of the cell can be 0.35 W/cm2 at 750℃.
