POLY (ARYLENE ETHER) COPOLYMER CONTAINING PYRIDINE UNITS AND ITS USE AS PROTON EXCHANGE MEMBRANES

摘要

The subject invention relates to the development and characterization of a new series of poly (arylene ether) copolymers containing pyridine and biphenyl or hydroquinone moieties. Preferred polymers can exhibit very good mechanical properties, high thermal and oxidative stability and high doping ability with strong acids. The invention further relates to the preparation and application of MEA on PEMFC type single cells.
