Title: Poly(aryl piperidinium) polymers for use as hydroxide exchange membranes and ionomers

Abstract

Poly(aryl piperidinium) polymers are provided which have an alkaline-stable cation, piperidinium, introduced into a rigid aromatic polymer backbone free of ether bonds. Hydroxide exchange membranes or hydroxide exchange ionomers formed from these polymers exhibit superior chemical stability, hydroxide conductivity, decreased water uptake, good solubility in selected solvents, and improved mechanical properties in an ambient dry state as compared to conventional hydroxide exchange membranes or ionomers. Hydroxide exchange membrane fuel cells comprising the poly(aryl piperidinium) polymers exhibit enhanced performance and durability at relatively high temperatures.
