In this present work, the effect of reduction temperature of Fe-Co-Ni/C anode catalyst on the solid alkaline fuel cell performance was investigated. Fe-Co-Ni/C anode catalysts were prepared by the impregnation method, and reduced at 360℃, 500℃, and 900℃ in hydrogen flow for 2 h. The order of the maximum power density was as follows: Fe-Co-Ni/C with reduction at 360℃ > reduction at 500℃ > reduction at 900℃. The maximum power density of 17 mW cm^[-2] was obtained for the cell with Fe-Co-Ni/C anode reduced at 360℃. The order of the particle size was as follows: Fe-Co-Ni/C with reduction at 360℃ < reduction at 500℃ < reduction at 900℃. Fe-Co-Ni/C reduced at 360℃ with the smallest particle size showed the highest activity for hydrogen oxidation reaction.
