A quasi three–dimensional model for PEM fuel cell impedance: The effect of local oxygen depletion under the flow field rib
Our previous 1d+1d model for PEM fuel cell impedance is extended to take into account 2d distribution of the oxygen concentration in the gas–diffusion layer under the flow field channel and rib. Fitting of the model impedance to the experimental spectra from the segmented PEMFC shows that in spite o...
