Anion-Conductive Multiblock Aromatic Copolymer Membranes: Structure-Property Relationships

摘要

Anion exchange membrane fuel cells (AEMFCs) are an alternative to proton exchange membrane fuel cells (PEMFCs) with potential benefits that include low cost (i.e., platinum-free), facile electrokinetics, low fuel crossover, and use of CO-resistant metal catalysts. Despite these advantages, AEMFCs have not been widely used because they require more highly conductive anion exchange membranes (AEMs) that do not exhibit impaired physical properties. With the objective of maximizing conductivity and stability, we developed a membrane material with a well-developed nanochannel structure.
