Abstract

Abstract : The membranes consisting of samaria-doped cerias, (SmO1.5 )0.2 (CeO2 )0.8 (SDC), containing 10~50 wt% nickel were formed by electrophoretic deposition (EPD). The membranes were examined as SOFC anodes fueled with 6% ammonia. The catalytic activity of ammonia decomposition was higher at lower Ni contents of 0~30 wt%. The anodic performances were similar between 10~40wt%. The impedance analysis of the anodes suggested that increase in the Ni content increased the resistance of electrochemical oxidation, and deceased in the low frequency component, which might be assigned to a molecular diffusion process.
