| Outline of Final Research Achievements |
Among several types of fuel cells, a solid oxide fuel cell (SOFC) can provide the highest electrical efficiency and have many kinds of cell geometries. In this study, we focused on a disk shape planar-type SOFC and designed a channel with circle involute shape current collectors. Swirling flow phenomena in a model disk channel with porous wall were investigated. In the case of applying circle involute shape current collectors made of porous metal, a rapid reduction of a velocity close to their surface was reduced. Furthermore, a velocity component normal to the current collector had positive value due to the gas flow permeating porous metal. These phenomena led to the discrepancy from the streamline along the involute curve. These characteristics were remarkable with increase in permeability and porosity of the current collectors. This result suggests that an optimum range of permeability and porosity of the current collector exists for favorable flow fields in the disk shape SOFC.
