An experimental analysis of the flow structure in various configurations of a circular-planar SOFC fuel channel

In the presented paper, the authors focus on the analysis of flow structure in various configurations of a circular-planar SOFC fuel channel. The research was carried out on the premise that a proper channel design would help minimize the thermal stress in the cell, which is affected by the heat generated and consumed by the reforming, water gas-shift and hydrogen consumption reactions. For the measurement process, PIV method was used to calculate the velocity fields, and an extensive error analysis was done to evaluate the accuracy of the calculated velocities.
