Description
Summary:This work describes the modification of the sulfonyl fluoride precursor of perfluorinated sulfonic acids (PFSAs) by the conversion of the sulfonyl fluoride group to a bis sulfonylimide group. The usefulness of these new polymers for fuel cell applications includes novel proton exchange membranes, catalyst additives or tie layers designed to be thermally and chemically robust while operating within a fuel cell's harsh environment at higher temperatures.
