Perfluorinated proton-exchange polymers form the basis of standard high-performance PEMFCs and PEM electrolyzers but difficult synthetic chemistry hampers further materials development. Hydrocarbon proton-exchange materials, on the other hand, are founded on well-established and versatile synthetic chemistry that allows for rapid materials development, and potentially offer a less expensive alternative to perfluorinated polymers. In the corollary case of Anion Exchange Membrane electrochemical technologies, the search continues for an alkaline-stable, polymeric hydroxide-conducting medium. Solutions to these challenges require the undertaking of rigorous systematic studies on model polymers and representative materials of known and controllable macromolecular structure. In this presentation, the evolution and properties of unique proton- and hydroxide-conducting polymers will be described.
