O-07　バイオマスガス化ガス組成がSOFCの発電性能に及ぼす影響

抄録

This study focuses on the operation of Ni-YSZ-based SOFC fueled with artificial fuel gas simulating syngas from biomass gasification. H₂, CO, CO₂ and H₂O were mixed to make up artificial fuel gas with various compositions. Electrochemical behaviors were investigated under constant current conditions at 1073K during 8h using Galvano-stat. Cyclic voltammetry was also conducted to assess the stability of SOFC. Measurement results showed that CO₂ and H₂O have significant impacts on power generation performance. In particular, the performance degradation was significant in the absence of CO₂.
