Abstract

Abstract

A steady-state two-phase heat and mass transfer model was developed for a single proton exchange membrane (PEM) electrolyzer to investigate the effects of different groove structures (triangular, tooth-shaped and goose-shaped) on its performance. The influence of groove depth, number and spacing was examined. The results show that incorporating grooves in the anode flow channel can improve electrochemical performance, enhance the heat and mass transfer, and increase the efficiency of the electrolyzer, with the best optimization effect of the goose-shaped groove. Within the range of 0.4~1.6 mm in depth, the electrolyzer corresponding to 0.8 mm has the best performance. Compared to a conventional flow channel, the optimized electrolyzer has a lower potential to achieve the same current density, has a better proportion of water saturation and oxygen content in the anode region, and has a lower proton exchange membrane temperature, thereby improving the performance of the electrolyzer.
