摘要：

Ceramic anodes comprising infiltrated SrMoO4 in porous ytttria-stabilized zirconia were investigated. Upon reduction at 1073 K, the electronically insulating SrMoO4 phase transformed to SrMoO3, which has a bulk electronic conductivity of 10(3) S cm(-1) under fuel cell conditions. An anode conductivity of 20 S cm(-1) was achieved with a low SrMoO4 loading of 13 vol % of the total anode. The infiltrated composite is dimensionally stable upon redox cycling, and a Pd catalyst was required to achieve good fuel cell performance. Fuel cell performance with methane was lower than with hydrogen. This lower methane performance could be due to coking. (C) 2010 The Electrochemical Society.
