abstract = {A model of PEM fuel cell impedance is developed taking into
account imposed harmonic perturbation of the air flow
velocity in the cathode channel. The flow velocity
modulation with the amplitude proportional to AC amplitude
of the cell potential lowers the resistivity Rh due to
oxygen transport in channel. When relative amplitudes of
velocity and potential oscillations are equal, a complete
compensation of Rh occurs. This effect explains experimental
findings of Kim et al.
(https://doi.org/10.1016/j.jpowsour.2008.06.069) and Hwang
et al. (https://doi.org/10.1016/j.ijhydene.2010.01.064), who
demonstrated significant improvement of PEM fuel cell
performance under oscillating air flow velocity.},
