A Model for Extraction of Spatially Resolved Data from Impedance Spectrum of a PEM Fuel Cell
2018
Journal of the Electrochemical Society
We report a novel approach to processing of impedance spectra of a PEM fuel cell. We split the cell into N virtual segments and let each segment to have its own set of transport and kinetic parameters. The impedance of a single segment is calculated using our recent physics-based impedance model; the segments are "linked" by equation for the oxygen mass balance in the cathode channel transporting the local phase and amplitude information from one segment to another. Thanks to this transport,
