Abstract: 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.
