Abstract: A proton exchange polymer comprises a polynorbornene copolymer with hydrophobic and hydrophilic blocks that can be phosphonated to produce phosphonic acid functional groups for proton exchange. Also, the polymer may be crosslinked to form quaternary ammonium groups on the side chains. The polynorbornene copolymer may be acid doped to ionically bond phosphonic acids to the quaternary ammonium groups that may for ion pairs for proton exchange. The proton exchange polymer has high temperature stability with the phosphonic acid functional group and can be mechanically durable with cross linking. Proton exchange membranes may utilize the proton exchange membrane in fuel cell and electrolyzer applications.

Abstract: An anion exchange branched co-polymer includes poly(aryl) and a branched compound and quinuclininuium side chains. The co-polymer may include xanthene or bibenzofuran. The anion exchange branched co-polymer may be more durable and have less creep and may have a higher ion exchange capacity (IEC) due to the structure and because some of the side chains may have multiple functional sites. The co-polymer may be cross-linked and may also include free radical inhibitors. The co-polymer may be incorporated into a support material and used in an anion exchange membrane or membrane electrode assembly.

Abstract: An ion exchange polymer has an ionomer structure containing poly(phenylene) compound integrated with functionalized poly(fluorene). The ion conducting co-polymer includes a poly(fluorene) compound and a poly(phenylene) compound covalently bonded together. The poly(fluorene) compound has a 9H-fluorene structure that is a polycyclic aromatic hydrocarbon having a center ring with five carbon atoms, and a benzene ring on each of opposing sides of said center ring. The poly(phenylene) compound is covalently bonded to each of the pair of benzene rings of the poly(fluorene) compound. A pair of sidechains extends from the center ring of the poly(fluorene) compound to a respective terminal group. The terminal groups are configured on sidechains of the poly(fluorene) compound and can be converted into functional groups such as quaternary ammonium or n-methyl piperidine functional groups. The ion exchange polymer may include a porous scaffold support.
