Youliang Cheng et al. propose a "2D Topology-Curvature Optimization" progressive design method to optimize the bend area structures of serpentine flow channels in PEMFCs. The method combines topology optimization with curvature optimization to improve the mass transfer and overall performance of the fuel cell. The researchers used numerical simulations to compare the topology-curvature optimization model with algorithm-based optimization models and a validation model. The study analyzed the mass transfer, heat transfer characteristics, and output performance of PEMFCs under different flow fields.
