Thin adsorbed Nafion films, representing ionomer in the PEMFC catalyst layer, were prepared by spontaneous adsorption of Nafion on SiO 2 model substrate. The conductivity of the thin films was examined over a wide range of temperature and relative humidity by electrochemical impedance spectroscopy. The activation energy of proton conduction was found to be twice and three-and-half times that...
