The paper deals with proton-conducting ionic liquids (PCILs) for use, in combination with functional polymers, in membranes operating in High Temperature PEMFC. Monoammoniums derived from monoamines and half-neutralized diamines were investigated in the form of triflates. Promising results were obtained with the half-neutralized diamine-based PCIL, its conduction being governed by both Grotthus-like and vehicular mechanisms, the respective contributions of which depend on temperature. In addition, their blending with Nafion results in a distinct reinforcement of the membrane.
