PEMEC双极板流场型式研究进展OA

Hydrogen energy has gained significant attention as an efficient energy carrier,distinguished by its high energy density,environmental sustainability,and clean emission-free characteristics.Elec-trolytic hydrogen production stands as a viable route for renewable energy integration and green hy-drogen generation.Among the four major water electrolysis technologies,proton exchange membrane water electrolysis(PEMWE)has become a prominent research focus due to its high current density,ef-ficiency in hydrogen production,high gas purity,low energy consumption,and reliable operational safety.As a critical component of the PEM electrolyzer,the bipolar plate serves not only as a structural support but also functions as a key element in electron conduction and reactant flow distribution.This review summarizes recent progress in flow field configurations for bipolar plates,with particular em-phasis on the influence of conventional and novel flow field designs on the heat and mass transfer per-formance of the electrolyzer.It further examines the application potential of artificial intelligence in flow field optimization and discusses future technological trends in bipolar plate development,thereby offering theoretical and practical guidance for the design of advanced flow field structures.
