| Research Abstract |
A solid oxide fuel cell (SOFC) is a high efficiency power generator and has recently been commercialized as a residential system. Cost reduction is one of the remaining problems. If the direct-internal reforming (DIR) of hydrocarbon fuel is successfully introduced to SOFC systems, the reformer can be eliminated from the system and the system cost will be lowered. Because of the strong endothermic nature of the reforming reaction, however, the DIR causes a severe temperature gradient in the system that may result in the cracks of the fragile ceramic cells. In this research, we investigated the effects of the microstructure of the SOFC porous anode on the reforming reaction. It was found that the gradual reforming reaction could be achieved by controlling the porous microstructure.
