520 _ _ |a We report a simple physics-based model leading to an analytical expression for impedance of the gas-diffusion layer (GDL) in a PEM fuel cell. We show that this expression differs from the classic Warburg finite-length impedance due to large double layer capacitance Cdl of a porous catalyst layer the GDL is attached to. It follows that the Warburg solution is obtained for the transport layer attached to a planar electrode with vanishingly small Cdl.
