Polymers with tethered cationic groups are being pursued for their potential to enable anion exchange membrane fuel cells. Critical to the design of these new anion exchange membranes is an understanding of the connection between the chemical structure of the polymer and its membrane transport properties and degradation behavior. We have studied anion exchange membranes with random and block copolymer structures based on poly(styrene) and poly(sulfone) backbones. This presentation will focus on the critical factors that control ion and water transport in these types of materials and provide some insights into their degradation behavior in ex-situ and in-situ environments.
