abstract = {We measure impedance of a standard Pt/C–based PEM fuel
cell for a series of current densities from 50 to 400 mA
cm− 2. Using our recent model for extraction of
spatially–resolved data from impedance spectra, we plot
the dependence of the oxygen diffusion coefficient Dox in
the cathode catalyst layer (CCL) and Db in the
gas–diffusion layer (GDL) on the distance along the
cathode channel. While the GDL oxygen diffusivity is fairly
uniform over the cell active area, the shape of Dox
indicates that the cell is separated into two domains with
high and low water contents in the CCL. We attribute this
effect to the positive feedback loop between the rates of
oxygen transport and liquid water evaporation in the CCL,
leading to local CCL flooding.},
