ABSTRACT:
An ion conductive membrane for electrochemical applications is provided for forming the membrane on the basis of a polyimide or copolyimide polymer, which contains in its structure heterocyclic groups, particularly in the form of imidazole-, pyridin or pyrimidin groups. The electrochemical applications include particularly the use of such membranes in fuel cells.
