Interfacial Regulation of Oxygen Transport in PEMFC Catalyst Layers by Functionalized Carbon Supports
and Pt surface, thereby reducing oxygen transport resistance. Moreover, the distance of functional group to Pt catalysts exhibits a nonmonotonic effect on the oxygen transport resistance: too close or too far from the Pt catalysts would weaken the effect of surface functional groups, while an optimal distance is around 7.38 Å, located outside the dense layer.
