Dependence of Electrode Proton Resistivity on Electrode Thickness and Ionomer Equivalent Weight in Cathode Catalyst Layer in PEM Fuel Cell

摘要

Dependence of electrode proton resistivity on electrode thickness, Pt-loading, and ionomer equivalent weight (EW) was investigated using Pt/Vulcan catalyst. The proton resistivity, an intrinsic electrode property, is independent of the electrode thickness and Pt-loading, but depends on the ionomer EW.
