The channel layouts on bipolar interconnects play an important role in improving the electrochemical performance of solid oxide fuel cells (SOFCs). Most previous layout design studies are performed based on artificial predetermination without optimization. In this study, a topologyoptimizationmethod for the flow channel layout of SOFCs based on the real microstructure of SOFC components is presented. Based on the reconstructed real microstructure, relevant numerical simulations are performed to analyze the multiphysics coupling mechanisms in SOFCs and provide an effective tool for SOFC performance prediction. To further improve SOFC performance, a numerical framework for flow field optimization based on the actual microstructure of a specific SOFC is proposed. The density-based topologyoptimization is used for the layout of the flow channels by coupling it with the multiphysical fields generated from electrochemical simulation coupled with flow field modeling. The optimization is modified based on the modification of the source term derived from the electrochemical simulation to achieve a significant improvement in the electrochemical performance of the SOFCs.
