摘要(Abstract):
采用溶胶凝胶法制备了La0.7Sr0.3Cr1-xMnxO3-δ(x=0.3,0.4,0.5,0.6)系列阳极粉体。在1000℃下焙烧后,XRD结果显示粉体物相为单一的钙钛矿相。制备以La0.7Sr0.3Cr1-xMnxO3-δ为阳极,Ce0.8Sm0.2O1.9(SDC)为电解质,Pr0.6Sr0.4Co0.8Fe0.2O3-δ-SDC复合阴极的电解质支撑型固体氧化物燃料单电池。由扫描电子显微镜(SEM)观察表明单电池电解质致密,阳极孔径分布均匀,厚度约为20μm,多孔阴极厚度为10μm。采用直流四电极法测试以La0.7Sr0.3Cr0.5Mn0.5O3-δ为阳极用湿氢气作燃料时在800℃下获得最大输出功率为232.84 mW.cm-2,短路电流为0.92 A.cm-2。
