Porous Media Of A Polymer Electrolyte
Membrane Fuel Cell

Abstract
Transport processes inside polymer electrolyte membrane fuel cells (PEMFC’s)
are highly complex and involve convective and diffusive multiphase,
multispecies flow through porous media along with heat and mass transfer and
electrochemical reactions in conjunction with water transport through an
electrolyte membrane. We will present a computational model of a PEMFC with
focus on capillary transport of water through the porous layers and phase change
and discuss the impact of the liquid phase boundary condition between the
porous gas diffusion layer and the flow channels, where water droplets can
emerge and be entrained into the gas stream.
Keywords: fuel cell modelling, multi-phase flow, GDL/channel interface.
