通过相转换流延结合浆料涂覆的方法制备了基于YSZ（氧化钇稳定的氧化锆）电解质的阳极支撑的平板固体氧化物燃料电池，电池阳极具有良好的非对称结构，包括较厚的指状大孔层和较薄的海绵状小孔层。以La0.8Sr0.2MnO3-δ-YSZ为阴极，电解质厚度为19μm的单电池获得了良好的性能输出，在600oC，650oC和700oC的最大功率密度分别为52MW/cm2，116MW/cm2和204MW/cm2，对应的开路电压分别为1.04V，1.02V和1.0V。结果表明：相转换流延结合浆料涂覆技术是一种非常有前景的阳极支撑的平板状SOFC制备方法。

Anode-supported planar solid oxide fuel cells (SOFCs) based on yttria-stabilized zirconia (YSZ) electro?lytes were prepared using phase inversion tape-casting and slurry coating techniques. The anodes of the cells have a good asymmetrical structure consisting of a thick layer with finger-like pores and a thin layer with small sponge-like pores. With La0.8Sr0.2MnO3-δ-YSZ (LSM-YSZ) as a cathode, the maximum power densities of the cell with a 19-μm-thick YSZ electrolyte film reached 52MW/cm2, 116MW/cm2, 206MW/cm2 at 600, 650℃ and 700℃ respectively with a good performance output, and the corresponding open-circuit voltages (OCVs) were 1.04V, 1.02V and 1 V. The results indicate that phase inversion tape-casing combined with slurry coating technique can be considered as a quite promising approach for cost-effective fabrication of anode-supported planar SOFCs.
