Abstract

Fe-doped (La,Sr)CrO_3-δ (LSCrFe) oxide was modified as the anode of solid oxide fuel cells. Through vacuum-assisted impregnation processes, nanosized Sm-doped CeO₂ (SDC) and Ni particles were introduced into an anode backbone. With Ni and SDC coimpregnated LSCrFe anodes, the maximum power densities at 900°C reached 765 and 271 mW cm^-2 with H ₂ and CH₄ as fuels, respectively, which were much higher than that with a nonmodified LSCrFe anode. Our results indicated that nanosized Ni particles played a primary role in performance enhancement. No carbon deposition was detected for all tested LSCrFe-based anodes.
