To improve the water management of proton exchange membrane fuel cell (PEMFC), the two-phase (liquid water and air) transport in the carbon-paper gas diffusion layer (GDL) of PEMFC was simulated and analyzed by using the pseudopotential multiphase lattice Boltzmann model (LBM), which mainly focused on the effects of GDL hydrophobicity on the two-phase transport. The results encompass: for a GDL of lower hydrophobicity, liquid water is easier to seep into the pore space, and thus reach a higher liquid saturation level in the GDL; while for a GDL of higher hydrophobicity, the liquid water can hardly enter the pores of smaller size, but flows along the pathways connecting the pores of relatively larger size, leading to the formation of a capillary-fingering flow.
