Proton-exchanging electrolyte membranes based on aromatic condensation polymers

The results of the research and development of novel proton-exchanging membranes based on aromatic condensation polymers have been analysed and summarized with respect to their application in fuel cells. Primary attention has been paid to the basic properties of the starting polymers, such as thermal stability, water uptake and proton conductivity. General approaches to the preparation of aromatic condensation polymers with high proton conductivity have been considered, including direct suffocation, synthesis from monomers containing sulfonic acid groups, incorporation of alkylsulfonated substituents and formation of acid-basic polymer complexes. The bibliography includes 200 references.
