A polymer electrolyte membrane is made from a polymer electrolyte and a coordination polymer, and finds use in a fuel cell. The polymer electrolyte membrane may be made by dissolving a polymer electrolyte in a solvent to provide a first solution, adding a coordination polymer to the first solution to yield a second solution, and forming the second solution into a film.

A method for the production of a functionalized polytriazole polymer, particularly a poly(1,2,4-triazole)-polymer, includes the steps of (a) mixing a hydrazine salt, particularly hydrazine sulfate, with at least an aromatic and/or heteroaromatic dicarboxylic acid and/or at least a dicarboxylic acid derivate in polyphosphoric acid and if necessary further components for obtaining a solution; (b) heating the solution in a protective gas atmosphere for obtaining polyhydrazides and adding aromatic and/or heteroaromatic primary amines to the solution; and (c) precipitating a polymer. If necessary, neutralization in a basic solution may be carried out.

A polymer electrolyte membrane includes a membrane polymer made of monomer units that have aromatic polyarylenes groups with proton-conducting functional groups bound to the aromatic polyarylene groups. The polymer electrolyte membrane can be used as a proton-conducting polymer membrane between the electrodes in a fuel cell.

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.
