abstract = {A three-dimensional (3D) lattice Boltzmann model is applied
to simulations of the dynamic process of liquid water moving
through the gas diffusion layer, processed by covering the
fibers with polytetrafluorethylene (PTFE), in polymer
electrolyte membrane fuel cells. The PTFE content and two
through-plane distribution styles were analyzed regarding
their impact on the liquid water's flow behavior. The total
saturation curves show that the water's breakthrough times
are affected by these two factors. Different characteristic
shapes of local saturation curves are observed with
different types of PTFE distribution. The dynamic elevation
plots of water fronts show that certain PTFE distribution
styles can be of advantage to fuel cell efficiency.},
