Abstract
In this study, an attempt has been made to study the effect of different flow field patterns in bipolar plates on the pressure drop and flow distribution of reactants in the proton exchange membrane fuel cell (PEMFC). Various patterns were designed in SolidWorks and analysed using computational fluid dynamics (CFD) in Ansys Fluent software to analyse the patterns created. The pressure drop and the flow distribution were studied and analysed. Results have proven that both serpentine and the parallel pattern are more suitable than any other pattern for improving the efficacy of PEMFC. It is imperative to note that serpentine model provides a uniform flow distribution at the cost of relatively increase in pressure drop, and on the other hand, in the parallel model the pressure drop is reduced at the cost of non-uniform flow distribution of reactants.
