Abstract

The proton conductivity of composites comprising dispersions of various types of nanometer-sized oxide particles in pure imidazole is investigated. The composite materials show significantly enhanced (up to a maximum of ten times in the case of sZrO2) ionic conductivity compared to pure imidazole. The reason is the formation of a space–charge layer on the oxide surface, as a consequence of adsorptive interaction.
