PROTON CONDUCTING AROMATIC POLYETHER TYPE COPOLYMERS BEARING MAIN AND SIDE CHAIN PYRIDINE GROUPS AND USE THEREFOR IN PROTON EXCHANGE MEMBRANE FUEL CELLS

摘要

New aromatic polyether type copolymers bearing main chain pyridine and side chain pyridine or pyrimidine units, which exhibit good mechanical properties, high thermal and oxidative stability, high doping ability and high conductivity values. The polymers are useful in the preparation and application of MEA on PEMFC type single cells. The polymers are, further, particularly suitable for use in high temperature PEM fuel cells.
