Microstructure reconstruction of the gas diffusion layer and analyses of the anisotropic transport properties

•Numerical and XCT 3D reconstruction are used to simulate Toray and Freudenberg GDLs.•Anisotropic transport properties and conductivity are obtained by Pore Scale Model.•Liquid water permeability and saturation are solved by Lattice Boltzmann Method.•Toray GDL has strong anisotropic properties due t...
