abstract = {A transient physical model for the PEM fuel cell cathode
catalyst layer (CCL) with fast proton and slow oxygen
transport is solved and an analytical expression for the
oxygen transport impedance is derived. This expression is
combined with the proton transport and faradaic impedances
of the PEMFC cathode reported previously. The resulting
analytical impedance includes the reaction activation and
the proton and oxygen transport losses in the CCL. Validity
of this impedance up to the typical working cell currents on
the order of several hundred mA cm−2 is demonstrated by
fitting the model equation to numerical impedance spectra
calculated from the full system of conservation equations.},
