Proton conductive poly(2-acrylamido-2-methyl-1-propanesulfonic acid) (PAMPS) ultrathin film was deposited as a multilayer on the size-controlled phenylsilsesquioxane (PhSiO3/2) particles via layer-by-layer (LbL) assembly. The composite electrolyte prepared from the PAMPS-multilayer deposited PhSiO3/2 had a grain boundary composed of the proton conductive multilayer. The interfacial conducting path having a honeycomb structure was percolated in the composite. The conductivity of the interfacial conducting path was estimated from general effective media (GEM) approximation. The interfacial conductivities of the composite under the conditions of 70 and 95%R.H. at 80°C were calculated from the fitting by GEM approximation to be 0.03 and 0.2 S cm−1, respectively.
