摘要：

Carbon deposition on a Ni-based anode is troublesome for the direct power generation from methane-based fuels using solid oxide fuel cell. In this paper, a redox-stable double-perovskite Sr2MoFeO6-delta (SMFO) is applied as an independent on-cell reforming catalyst over a Ni-YSZ anode to improve coking resistance. The morphology, catalytic activity and electrochemical performance for wet methane/coal-bed gas (CBG) are investigated. A Ni-YSZ anode supported cell with SMFO generates a high power output of 1.77 W center dot cm(-2) and exhibits favorable stability operated on wet CH4 at 800 degrees C. Post-mortem micro-structural analyses of cells indicate the cell operated on CBG shows coking probably due to the heavy carbon compounds in CBG.
