ABSTRACT:
The invention relates to a modified polybenzimidazole (PBI), membranes that are fabricated from these polymers, and their use in electrochemical applications. These membranes have high ionic conductivity and are suitable for solid polymer electrolytes in electrochemical applications, especially for high temperature polymer electrolyte membrane (PEM) fuel cells.
