Experimental impedance spectra of a segmented PEM fuel cell are fitted using a numerical impedance model based on the transient macrohomogeneous equations for the cathode side. Dependence of the cell transport and kinetic parameters on the current density is reported in the range from 50 to 400 mA cm−2. The largest variation (growth by an order of magnitude) exhibit the cathode catalyst layer proton conductivity σp and oxygen diffusivity. Moreover, σp exhibits a stepwise change at the current density ≃ 200 mA cm−2. This jump could lead to formation of current-carrying and current-free zones over the cell surface. Recent experimental data (JES, 156, B301 (2009)) show that this configuration is indeed realized in PEMFCs with the high- and low-current density zones under the channel and rib, respectively.

Oxygen transport resistivity of the cathode catalyst layer in a low–Pt PEM fuel cell has been determined using two methods: the first one is fitting of our recent physics–based impedance model to the experimental impedance spectra of the cell, and the second is calculation of distribution of relaxation times (DRT) using the same spectra. Comparison of the two methods shows that the DRT peak with the characteristic frequency on the order of 500 to 1000 Hz describes oxygen transport in the open pore and in Nafion film covering Pt/C agglomerates in the catalyst layer. This result makes it possible using experimental impedance spectroscopy and DRT calculation for routine measurements of cathode transport resistivity in low–Pt PEMFCs.
