An experimental study has been performed to investigate the radial flow phenomena in a disk-shape channel which simulate a gas flow in a disk-shape planar-type Solid Oxide Fuel Cell (SOFC). In the planar-type SOFC, a reduction of thermal stress is one of the important issues. A temperature distribution in the planar-type SOFC is strongly affected by the gas flow behavior, and hence we tried to clarify flow pattern at various mass flow rate by using of particle image velocimetry (PIV). In the present study, it was found that a uniform flow distribution in the fuel channel was attained in the case of Reynolds number of 4 to 7. On the other hand, non-uniform flow distribution was enlarged with increase of flow rate in the air channel. These results suggest the optimum flow conditions expected in the disk-shape SOFC.
