The use of fuel cells to produce electricity are known as an environmentally clean and reliable source of energy, and show promise as an automotive power source if the polymer electrolyte membrane fuel cell can be made less expensive, more durable, reduce or eliminate humidification of the reactive gases, and operate at temperatures encountered during automotive operating conditions. The use of an electro-catalyst formed from heteropoly acids immobilized by a conductive material, such as carbon or platinum black, and stabilizing a metallic black with the immobilized conductive material addressed these automotive fuel cell needs. Coating the fuel cell electrode, polymer electrolyte assembly with a nano-particle catalyst derived from a heteropoly acid provided anodic carbon monoxide tolerance at anodic overpotentials and an active cathodic oxygen reduction. The heteropoly acids can also function as supercapacitor electrode films.

This disclosure provides polymer electrolytes, polymer electrolyte membranes (PEM's) and membrane electrode assemblies (MEA's) such as may be useful in fuel cells which contain or comprise polyoxometalates (POM's) or heteropolyacids (HPA's). In some embodiments the polyoxometalate, it's counterions or both may comprise Mn and/or Ce. In some embodiments the polymer electrolyte is fluorinated. In some embodiments the polymer electrolyte comprises a second acidic functional group other than a polyoxometalate. In another aspect, the present disclosure provides methods of making polymer electrolytes including methods which comprising a step of copolymerizing monomers comprising a covalently bound polyoxometalates and methods which comprise a step of covalently attaching a polyoxometalate to the polymer.
