Decoupling Interfacial Proton Conductivity in Ionomer Thin Films on Pt and Carbon Electrodes
, carbon and Pt supports were of the same order of magnitude, with only modest differences (within a factor of about two) among them, while remaining highly reproducible across IDE geometries. This methodology provides the first geometry-independent framework for quantifying proton transport at individual interfaces in supported ionomer films under an inert atmosphere.
