A physicsbased numerical model for fitting local impedance spectra local impedance model, LIM of the segmented PEM fuel cellis developed and used to validate our recent model for recovery of local parameters from a single spectrum of the whole cell cellimpedance model, CIM. Shapes of the local parameters along the cathode channel resulting from the two models are compared.Overall, the CIM quite satisfactorily describes the cell local parameters provided that the oxygen transport impedance in the channelis not small as compared to other impedances in the cell.
