In the present study, we investigated a swirling flow structure in the model channel of a disk shape planar solid oxide fuel cell (SOFC) to realize the flow uniformity by the optimization of flow passage. A particle image velocimetry (PIV) was used to provide a description of the velocity fields. In the case of applying circle involute shape current collectors, a flow uniformity was achieved over the wide range of Reynolds numbers. This is because a flow passage consisting of two adjacent involute curves functions as a constant-area channel. An estimation of a swirling fluid motion in the channel was carried out by using Euler's equation of motion. We confirmed that the velocity component in the flow direction is dominant and plays primary role to maintain a swirl motion.
