Abstract The performance and stability of proton exchange membrane fuel cells are mainly dependent on mass transports in the gas diffusion layer (GDL). dual‐region including regions under‐channel under‐rib one factors that cause uneven distribution. Therefore, wave structure auxiliary flow channel introduced to enhance these transports. Auxiliary conventional parallel field (ACPFF), (WFF), WFF (AWFF) transferred into ANSYS MESHING for meshing, then imported Fuel Cell Electrolysis module FLUENT solution. This comprehensive AWFF has important influences even distribution performance. results reveal forced convections can be made by periodic waved channel. More reactants appear GDL under‐rib. Based simulation results, distributions oxygen, water, temperature more AWFF. Specifically, cell at high current density is improved obviously. Compared CPFF, max power increased than 4% this novel (AWFF), which will provide a new trial design field.
