  • Method of fabricating an electrolyte material
    Patent number: 9663600
    Abstract: A method of fabricating low EW, water insoluble electrolyte materials includes providing a perfluorinated polymer resin that includes perfluorinated carbon-carbon backbone chain and sulfonyl fluoride ended perfluorinated side chains, extending from the perfluorinated backbone chains via an ether linkage, exposing the perfluorinated polymer resin to ammonia gas to convert the sulfonyl fluoride groups to sulfonamide groups, —SO2—NH2, which reacts with sulfonyl fluoride containing chemical agent(s) to form sulfonimide groups, and at the same time, generates low EW, 3-dimensional cross-linked, water-insoluble perfluorinated polymer electrolyte materials.
    Type: Grant
    Filed: December 21, 2012
    Date of Patent: May 30, 2017
    Assignees: Audi AG, Toyota Jidosha Kabushiki Kaisha, The Board of Trustees of the University of Alabama

  • PROTON EXCHANGE MATERIAL AND METHOD THEREFOR
    Publication number: 20130281555
    Abstract: A proton exchange material includes perfluorinated carbon backbone chains and side chains extending off of the perfluorinated carbon backbone chains. The perfluorinated side chains include cross-link chains that have multiple sulfonimide groups, —SO2—NH—SO2—.
