Proton exchange membrane (PEM) electrolysis for hydrogen production has broad application prospects, but it still has disadvantages such as high equipment cost and insufficient durability. Optimizing the flow channel can improve the uniformity of water and heat distribution in PEM and extend the service life of the electrolyzer. To enhance the performance of PEM, a three-dimensional wavy flow channel model was designed and simulated using COMSOL simulation software. The polarization curves, distribution of reactants and products, and temperature distribution of electrolyzers with different frequency wavy structures were studied, and the influence of flow rate changes due to the addition of wavy structures on the performance of the electrolyzer was explored. The results show that, compared with the conventional rectangular flow channel, the electrolyzer with wavy flow channels has significantly enhanced the heat and mass transfer effects and got better polarization performance. When the wavy frequency is 1.0, the current density of the electrolyzer increases by 2.1%, and the average gas volume fraction in the anode catalyst layer decreases by 3.7%, achieving the best overall performance. This study can provide certain references for the flow channel design of PEM electrolyzers.
