N2 - When the assembly force is applied, the gas diffusion layer (GDL) deformation is observed and the geometry and transport parameters are also changed. Accordingly, the transport processes and cell performance are affected due to the deformation effect. In the present study, a three-dimensional, non-isothermal, two-phase flow model was developed and applied to investigate the effect of GDL deformation on transport phenomena in Proton exchange membrane (PEM) fuel cells with interdigitated flow channels. The current densities, liquid water saturation distributions, and oxygen concentration distributions for PEM fuel cells with homogeneous and inhomogeneous compression are presented and compared.
