Investigation of the Effect Mixed Hydrophilic and Hydrophobic Fibers in the Gas Diffusion Layer of a Polymer Electrolyte Membrane Fuel Cell
In this study, Lattice Boltzmann method (LBM) is used to investigate liquid water transport in a gas diffusion layer (GDL) and gas channel (GC) of polymer electrolyte membrane of cathode fuel cells. In this paper,behavior of liquid water clusters from catalyst layer / GDL interface to gas channel is studied and the dynamic behavior of liquid water during removal from gas diffusion layer (GDL) of a PEMFC cathode electrode is simulated.Also, the effects of mixed wettability on the liquid water dynamic behavior distribution in the GDL and liquid water saturation within the GDL in steady state and transient are investigated. The results show that the best performance is obtained when the hydrophilic pores are placed closer to GDL-GC interface.
