Investigating design parameters of a perforated metal gas diffusion layer in a polymer electrolyte membrane fuel cell

The effect of the metal-gas diffusion layer (M-GDL) on the performance of a proton exchange membrane fuel cell (PEMFC) was investigated by numerically simulating selected parameters. Even though the ability of the M-GDL to outperform the conventional GDL is well known, it is necessary to optimise the design parameters of the M-DGL. This is to address its inefficient gas and electron transport due to the inherent heterogeneous structure. This...
