Abstract

Sn-NiO-Ce0.8Sm0.2O1.9 (SDC) is synthesized as an anode material for solid oxide fuel cells with H2 and dry methane as fuels. Sn-Ni alloy is formed after reduction. The performances of anode-supported single cells with a configuration of Sn-Ni-SDC|SDC|Ba0.5Sr0.5Co0.8Fe0.2O3-δ are investigated in the range of 600–700 °C. With increasing Sn content of the anode, the performances of the cells fed with H2 and dry methane both decrease slightly, indicating a reduced anodic catalytic activity. However, the stability of the cell with dry methane as fuel improves remarkably with the addition of Sn due to the suppression of carbon deposition on the anode.
