摘　　要：采用硝酸盐-柠檬酸法合成了具有高比表面积的一系列Ni-Fe氧化物和电解质Ce0.8Sm0.2O1.9(SDC),利用上述材料制备出固体氧化物燃料电池(SOFC)复合阳极材料Ni-Fe/SDC,并对其微结构和相关性能进行测试.结果表明:该复合阳极材料与电解质SDC具有较高的热匹配性,以其作为SOFC的阳极,氢气为燃料,其单电池表现出优异的性能,700℃电池输出功率密度最高可达90.6mW·cm-2.A series of Ni-Fe oxides with high specific area and Ce0.8Sm0.2O1.9（SDC） electrolyte were prepared using the nitrate-citric acid method. On the basis of Ni-Fe oxides and Ce0.8Sm0.2O1.9 electrolyte, Ni-Fe/SDC composite anode materials were prepared. Meanwhile, their microstructure and other performance-related parameters were also tested. The results showed that the thermal expansion of the composite anode materials matched well with that of the SDC electrolyte. Furthermore, the single cell, using hydrogen fuel and the composite materials as the anode of solid oxides fuel cell（SOFC）, showed an excellent electrochemical performance with hydrogen fuel. At 700℃, the maximal power density was 90.6 mW·cm^-2.
