Patent

CA 2546484

A novel polymer electrolyte is provided that enables a solid polymer electrolyte used in fuel cells, for example, to have sufficient proton conductivity even in a low-water-content state or a zero-water-content state by using a monomer compound represented by the general formula (1), and a graft copolymer compound in which the monomer compound represented by the general formula (1) is graft-copolymerized to the main chain of a fluorine- containing hydrocarbon polymer. Tf indicates a trifluoromethane sulfonyl group (-SO2CF3).

La présente invention concerne un nouvel électrolyte polymère qui permet à un électrolyte polymère solide utilisé dans des piles combustibles, par exemple, de posséder une conductivité de protons suffisante même dans un état de faible contenu d'eau ou dans un état de contenu d'eau nul par l'utilisation d'un composé monomère représenté par la formule générale (1) et, un composé copolymère greffé dans lequel le composé monomère représenté par la formule générale (1) est copolymérisé et greffé à la chaîne principale de polymère d'hydrocarbure contenant du fluor. Tf indique un groupe trifluorométhane sulfonyle (-SO2CF3).
