abstract = {We report a novel approach to processing of impedance
spectra of a PEM fuel cell. We split the cell into N virtual
segments andlet each segment to have its own set of
transport and kinetic parameters. The impedance of a single
segment is calculated using ourrecent physics–based
impedance model; the segments are “linked” by equation
for the oxygen mass balance in the cathode
channeltransporting the local phase and amplitude
information from one segment to another. Thanks to this
transport, the total cell impedancecontains information on
the local transport and kinetic properties of the cell. We
show that fitting the model cell impedance to
theexperimental spectra yields the parameters of individual
segments, i.e., the shape of the cell physical parameters
along the cathodechannel.},
