摘要

This study presents a numerical investigation on the cell performance enhancement of a proton exchange membrane fuel cell (PEMFC) using the finite element method (FEM). The cell performance enhancement in this study has been accomplished by the transverse installation of a baffle plate and a rectangular block for the modification of flow pattern in the flow channel of the fuel cell. The baffle plates (various gap ratios, λ = 0.005-10) and the rectangular block (constant gap ratio, λ = 0.2) are installed along the same gas diffusion layer (GDL) in the channel at constant Reynolds number for the purpose of investigating the cell performance. The results show that the transverse installation of a baffle plate and a rectangular block in the fuel flow channel can effectively enhance the local cell performance of a PEMFC. Besides, the effect of a rectangular block on the overall cell performance is more obvious than a baffle plate.
