摘要：

La0.8Sr0.2Ga0.8Mg0.2O3-delta (LSGM)-electrolyte-supported solid oxide fuel cells (SOFCs)with Cu-CeO2-LSGM anodes were fabricated, and their performance, while operating on H-2 and C4H10, was characterized. The cells demonstrated the ability to directly operate on both hydrogen and butane fuels between 600 and 700 degreesC. At 700 degreesC, a cell with a 440-mum thick electrolyte had maximum power densities of 220 and 115 mW/cm(2) for H-2 and C4H10 fuels, respectively. Impedance study indicates that the Cu-CeO2-LSGM anodes limit cell performance. (C) 2004 Published by Elsevier B.V.
