Fluorinated Poly(aryl piperidinium) Membranes for Anion Exchange Membrane Fuel Cells

Abstract Anion‐exchange‐membrane fuel cells (AEMFCs) are a cost‐effective alternative to proton‐exchange‐membrane fuel cells (PEMFCs). The development of high‐performance and durable AEMFCs requires highly conductive and robust anion‐exchange membranes (AEMs). However, AEMs generally exhibit a trade‐off between conductivity and dimensional stability. Here, a fluorination strategy to create a phase‐separated morphological structure in poly(aryl piperidinium) AEMs is reported. The highly hydrophobic perfluoroalkyl side chains augment phase separation to construct interconnected hydrophilic channels for anion transport. As a result, these fluorinated PAP (FPAP) AEMs simultaneously possess high conductivity…
