      abstract     = {Impedance spectra of a PEM fuel cell with three Fe-N-C
                      cathodes have been measured under the H2/N2 testing regime.
                      The spectra have been fitted using a recently developed
                      physics-based impedance model, which takes into account
                      finite proton (σp) and electron (σe) conductivity of the
                      oxygen-free cathode catalyst layer. Fitting allowed to
                      extract numerical data for σp, σe, the double layer
                      capacitance, and the inductance of cables used for measuring
                      impedance spectra. The values of σp and σe are close to
                      what previously found for standard Pt/C electrodes, which is
                      found for the first time using PGM-free catalysts. The
                      method enables simultaneous measurement of reference proton
                      and electron conductivity of PEMFC cathode.},
