Featured are novel heterocycle substituted hydroquinones, aromatic copolymers and homopolymers bearing main and side chain polar pyridine units. These polymers exhibit good mechanical properties, high thermal and oxidative stability, high doping ability and high conductivity values. These novel polymers can be used in the preparation and application of MEA on PEMFC type single cells. The combination of the above mentioned properties indicate the potential of the newly prepared materials to be used as electrolytes in high temperature PEM fuel cells.
