PEMFCs multiscale modeling: Determination of overpotential with description of electron transfer in cathodic EDL at different O2 concentrations

The effect of the formation of the electrical double layer (EDL) as a function of O2 concentrations in Pt/H2O interface in a proton-exchange membrane fuel cell (PEMFC) is analyzed in this work. The overpotential associated with the existence of the EDL is calculated at typical fuel cell O2 concentra...
