Bimetaloxides Ni1-xFexO (x = 0.01, 0.04, 0.08, 0.1, 0.15, 0.2, 0.4, 0.5) were synthesized and studied as anodes for intermediate temperature solid oxide fuel cells (SOFCs) based on yttria-stabilized zirconia (YSZ) film electrolyte. A single cell consisted of Ni1-xFexO-YSZ anode, YSZ electrolyte film, LSM-YSZ composite cathode was prepared and tested at the temperature from 600 degrees C to 850 degrees C with humidified hydrogen (75 ml min(-1)) as fuel and ambient air as oxidant. It was found that the cell with Ni0.9Fe0.1O-YSZ anode showed the highest power density, 1.238 W cm(-2) at 850 degrees C, among the cells with different anode composition. The promising performance of Ni1-xFexO as anode suggests that bimetal anodes are worth studied for SOFCs in future.
