Proton Exchange Membrane Fuel Cell Flow Field Configuration: Modelling and Experimental Verification

Improper design of flow field channels may lead to water stagnation and flooding and may therefore lead to a poor fuel cell performance. The main purpose of this work is to investigate liquid water formation inside the flow field of the proton exchange membrane (PEM) fuel cell and to find optimal flow field configuration such as: number of channels, channel width to rib ratio and channel depth. To achieve this goal advanced numerical model of PEM fuel cell was developed. Model was simulated in Fluent, using computational fluid dynamics (CFD). Based on the obtained simulation results, graphite bipolar plate with optimal channel design was machined, integrated into the single PEM fuel cell unit, and experimentally tested.
