The use of coal syngas as fuel to drive SOFC is one of the attractive options for efficient power generation(e.g. IGFC: Integrated Gasification Fuel Cell Combined Cycle). It would be necessary to clarify the complex effects of trace impurities contained in the coal syngas on the stability in performance and the chemical/physical constitution of SOFC anode and electrode. Power generation as well as exposure experiments were carried out with a button-shaped single SOFC cell. A SEM-EDX observation confirmed that micro-scale change in morphology and chemical composition of SOFC anode. Recoverable and unrecoverable performance losses were observed during our exposure tests suggesting the occurrence of various chemical interactions between trace impurities in fuel gas and active site of SOFC anode.
