以有机基流延工艺制备出了不同Ni含量的NiO/Sm0.2Ce0.8OO1.9(NiO/SCO)燃料电池阳极支撑体膜.研究了制备工艺条件和Ni含量等因素对阳极膜微结构和性能的影响.试验结果表明:NiO/SCO流延生坯的烧结温度对最终阳极烧结体的孔隙特性有着决定的影响;为获得具有较高孔隙率和一定孔径分布的阳极烧结体,生坯的烧结温度应不超过1 350℃;此外,不同含Ni量阳极流延生坯的烧结行为及烧结体的性能也存在明显的差异,在相同的烧结温度下,高含Ni量阳极烧结体的孔隙率和孔径都明显小于低含Ni量的烧结体,其晶粒的平均尺寸则增大.对不同温度下Ni/SCO阳极电导率的测量结果则表明,Ni/SCO阳极的导电性能也与其Ni含量和制备工艺有着密切的关系.
