abstract = {A model for impedance of a PEM fuel cell cathode taking
into account oxygen transport in the cathode catalyst layer
(CCL), gas–diffusion layer (GDL) and in channel is solved
analytically. A formula for the cathode impedance is valid
for the cell current densities below 100 mA cm−2 and air
flow stoichiometries exceeding 10. Least–squares fitting
of experimental spectrum using the analytical result takes
about 5 s on a standard PC. Fitting returns Tafel slope of
the oxygen reduction reaction, double layer capacitance, CCL
proton conductivity and oxygen diffusivities of the CCL and
GDL. Analytical impedance can be coded as a user–defined
function for a standard spectra fitting software supplied
with EIS–meters.},
