Mass transport over-potential is the major barrier to achieving high performance at a high current density. Condensed water, specifically in the gas diffusion layer (GDL), reduces oxygen transport to the oxygen reduction reaction (ORR) area. Experimental investigations of oxygen transport are limited by an inability to resolve the water saturation-dependent properties.

The flow-field bipolar plates and membrane electrode assembly (MEA) models are calculated using traditional computational fluid dynamics (CFD) method with existing PEMFC model; whereas the detail structured GDLs are numerically predicted by Lattice Bolzmann method (LBM).
