摘要：

Sm0.95Ce0.05Fe1-xNixO3-delta (x=0-0.05) perovskite materials were investigated for their candidacy as anodes for Low temperature Solid Oxide Fuel Cell (LT-SOFC). Electrolyte supported button cells were made and tested with hydrogen and dry methane fuels. A three-electrode geometry was used and electrochemical impedance measurements were carried out revealing that Ni doping does improve the performance of the resulting anodes as indicated by a decrease in charge transfer resistance values. The value of charge transfer resistance is lowest for x=0.03 (1.65 Omega cm(2) at 600 degrees C) and only light coking was observed.
