In particular, different studies investigated the flow uniformity in various interconnects and its influence on cell performance of the SOFC; including a transparent hydraulic platform that was used to measure flow uniformity in different rib-channel modules of interconnects The models implemented by CFD packages were established first to model these hydraulic experiments, and then used to calculate the cell performance of a single-cell stack using different designs of interconnects with different flow uniformity over a wide range of a hydraulic Reynolds number (Re) based on a hydraulic diameter of rib-channels. Numerical analyses demonstrate a strong influence of Re on cell performance, of which appropriate ranges of Re in both anode and cathode sides are identified an economic fuel utilization rate and having less temperature variations in the single-cell stack
