abstract = {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.},
