abstract = {Placing a catalyst layer between two membranes in a PEM
fuel cell one gets a membrane–electrode assembly with
inactive catalyst layer (ICL). A model for ICL impedance is
developed taking into account finite electron conductivity
of the layer. Analytical expression for the ICL impedance is
derived. Analysis of characteristic features of the ICL
Nyquist spectrum leads to simple analytical expressions for
the high–frequency and polarization resistivity, for the
summit frequency and for the straight high–frequency part
of the spectrum. The results allow to estimate the ICL
proton and electron conductivities and double layer
capacitance without complicated curve fitting.},
