Abstract

The influence of chemical species, water vapor and SOx, included in air on the voltage drop of SOFCs was studied. La2O3 was formed on the surface of cathode and caused the significant voltage drop of cells under high water vapor concentrations at 800°. The voltage drop of cells also occurred with SO2 in air but was recovered with supplying SO 2-free air into the cells. It was considered that the cell voltage drop caused by SOx was due to the adsorption of sulfur and/or the formation of sulfur compounds on the surface of cathodes.
