Evaluates ionic liquid- and polymer-based membranes for better proton conduction, suggesting improved fuel cell performance.
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‐neutralised diamines were investigated in the form of triflates. Promising results were obtained with the half‐neutralised diamine‐based PCIL, its conduction being governed by both Grotthuss‐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.
