| Outline of Final Research Achievements |
A biomass gasification and fuel cell power generation system is a promising technology for small-scale plants whose capacity is less than 1 MW. However, trace tar in syngas from biomass brings carbon deposition and anode deterioration. Therefore, a robust electrode catalyst against tar is necessary. In this study, Ni-Cu alloy, Ni-Fe alloy and Ni-CeO2 composite electrode catalyst were applied for electrode catalyst for anode in SOFC, and these carbon deposition behavior and power generation performances were evaluated. In the three electrode catalysts, Ni-CeO2 composite catalyst was best not only carbon deposition behavior, but also power generation performance. Especially, in the case of Ce : Ni ratio was 1 : 9, carbon deposition from toluene as a model tar was not observed and power out-put of the cell exceeded that of a conventional single cell. Therefore, Ni-CeO2 electrode catalyst whose ratio is Ce:Ni = 1:9 is best for a biomass gasification and fuel cell power generation system.
