%X Impedance spectra of a commercial polymer electrolyte membrane fuel cell (PEMFC) stack are analyzed by means of fitting a physics-based model and distribution of relaxation times (DRT) techniques. Oxygen transport coefficients of the gas-diffusion layer, the cathode catalyst layer (CCL), and the CCL proton conductivity are determined for the stack current densities of 150, 250, and 400 mA cm–2. DRT function returns reaction resistivity and transport resistivites of the channel and porous layers. A good agreement between the transport parameters resulting from the fitted model and DRT is demonstrated.
