| Abstract: | Bimetal oxides 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 °C to 850 °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 °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. |
