WebDec 11, 2024 · As a key component of proton exchange membrane (PEM) fuel cell, gas diffusion layer (GDL) plays an important role in mass transport process. In this study, the layered setting method is used to cut the GDL along the thickness direction, and the porosity of different layers is set to make it have porosity distribution along the thickness direction. WebAug 11, 2024 · Gas Diffusion Layers (GDL) are one of the components in different types of fuel cells including, but not limited, to Proton Exchange Membrane and Direct Methanol fuel cells. Gas Diffusion Layers serve to provide conductivity in the cell and control the contact between the reactant gases and the catalyst.This layer also aids in managing the water … WebGas Diffusion Layers. The GDLs sit outside the catalyst layers and facilitate transport of reactants into the catalyst layer, as well as removal of product water. Each GDL is typically composed of a sheet of carbon paper in which the carbon fibers are partially coated with polytetrafluoroethylene (PTFE). Gases diffuse rapidly through the pores ... loctite gasket sealant black
