摘要: Abstract A pore-network model was developed to study the water transport in hydrophobic gas diffusion layers (GDLs) of polymer electrolyte membrane fuel cells (PEMFCs). The pore structure GDL materials modeled as a regular cubic network pores connected by throats. governing equations for two-phase flow were obtained considering capillary pressure pores, and entry viscous drop through Numerical results showed that saturation distribution GDLs maintained concave shape, indicating strongly influenced processes. Parametric studies also conducted examine effects several geometrical properties on behavior distribution. proper inlet boundary condition liquid entering discussed along with its
