摘要：
Single-chamber solid oxide fuel cells (SOFCs) with an anode-supported Ce0.9Gd0.1O1.95 electrolyte were operated in a mixture of butane and air at furnace temperatures of 200-300 degrees C. The electromotive force (emf) of the cell and the voltage drop were strongly influenced by the catalytic activity of the anode for the partial oxidation of butane. The promotion of hydrogen formation by the addition of Ru to the anode caused an increase in the emf and a reduction in the voltage drop. As a result, stable power densities of 44 and 176 mW cm(-2) were obtained at 200 and 300 degrees C, respectively. (C) 2004 The Electrochemical Society.
