Outline of Final Research Achievements

Based on the molecular design principle (i.e., no heteroatom linkages in the polymer main chain), a novel fluorine-free aromatic ionomer membrane has been designed and synthesized. Compared with the existing perfluorinated or aromatic (i.e., containing heteroatom linkages in the polymer main chain) ionomer membrane, the novel membrane exhibited higher proton conductivity and chemical stability. In addition, the membrane also exhibited high fuel cell performance, with excellent durability under practical conditions.
