Abstract
Proton exchange membrane fuel cells are widely used in the field of electric vehicles, and the flow field design has an important impact on the performance of the battery. In this paper, the effects of three different flow fields on the gas distribution, temperature distribution and water removal performance of the battery were studied through three-dimensional multiphase and multiphysical field numerical simulation. The results show that the slot flow field design can significantly enhance the lateral mass transfer under the ribs. Compared with the parallel flow field, the uniformity of the distribution of gas, temperature, current density and liquid water is significantly improved, and the performance is improved.
