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 cath...
