abstract = {Analytical model for concentration/pressure (zeta)
impedance of the cathode side of a PEM fuel cell is
developed. The model is based on transient oxygen mass
transport equations through the gas-diffusion and cathode
catalyst layers. Analytical solution for zeta-impedance is
derived and the relation of zeta-impedance and regular cell
impedance is obtained. In the limit of high oxygen
consumption in the catalyst layer, simple equations for the
static point of zeta impedance are derived. These equations
allow one to estimate oxygen transport coefficients of the
catalyst and gas diffusion layers from the static point of
zeta-spectrum. Qualitative resemblance of the model and
experimental zeta-spectrum is demonstrated.},
