The aim of this paper is to examine the feasibility of Y0.9Sr0.1Cr1-xFexO3-delta for potential use as anode materials in solid oxide fuel cells (SOFCs) fed with fuel gas containing H2S, as well as other electrochemical devise. Y0.9Sr0.1Cr1-xFexO3-delta (x = 0.1, 0.3, 0.5) were synthesized by gel combustion method and had single-phase orthorhombic perovskite structure. These materials were all stable in reducing atmosphere (10%, v/v H-2/N-2) up to 800 degrees C. By the comparison of the O 1s peaks assigned to Y0.9Sr0.1Cr1-xFexO3-delta before and after reduction in H-2/N-2, lower content of lattice oxygen and higher content of adsorbed oxygen were observed for Y0.9Sr0.1Cr0.9Fe0.1O3-delta, while others appeared opposite results. This phenomenon suggested that reduced Y0.9Sr0.1Cr0.9Fe0.1O3-delta could capture oxygen when exposure to air, which is essential for anode materials. Moreover, Y0.9Sr0.1Cr0.9Fe0.1O3-delta maintained good chemical stability under H2S-containing atmosphere through XRD and FT-IR analysis. So Y0.9Sr0.1Cr0.9Fe0.1O3-delta was suggested as a promising anode material for SOFCs fed with fuel gas containing H2S. (C) 2012 Elsevier B. V. All rights reserved.
