In recent years, protections of environmental pollution and global warming are most important issues to discuss the world energy use. Efficient and clean use of fossil energy resources in the world has been increasing in importance. Coal is produced all over the world also, and it amount of reserves is larger than any other fossil fuels (oil, natural gas, etc.). Consequently, IGFC (Integrated gasification fuel cell combined cycle) has been attracting attention as one of efficient coal utilization. However, trace elements in coal are emitted to coal syn-gas in vapor phase, and affect fuel cell electrodes to deteriorate their performances. In this study, we assess the effect of trace element in syn-gas on SOFC power generation. We have tested a button cell in 900℃ for about 20 hours with simulated gas doped vapor As and Se.
