Determination of Permeability of the Gas Diffusion Layer of Proton Exchange Membrane Fuel Cells (PEMFCs)

One vital component in the Proton Exchange Membrane Fuel Cells (PEMFCs) is the Gas Diffusion Layer (GDL). This layer is a pathway for the reactants to reach the reaction site and for the by-products to be removed. Due to this application, the permeability of this layer has been investigated experimentally and numerically [1]. This layer has a highly porous structure, and hence identifying a geometry that resembles best the GDL for modeling flow …
