NOVELTY - High tolerance fuel cell membrane formed by a perfluoro ion exchange resin, comprises at least one of degradable oxygen-derived free radical additive. The perfluoro ion exchange resin is at least one of perfluorosulfonic acid resin and perfluorophosphoric acid resin, perfluorosulfonic acid-perfluorophosphoric acid copolymer resin. The free radical additive is e.g. 3-(3,4-dihydroxyphenyl)acrylaldehyde compound (VI), 4,6-dihydroxy quinoline or derivatives (VII), quinolinyl-boronic acid compound (VIII), and isoquinolinyl boronic acid compound (IX).    USE - Used as a fuel cell membrane.    ADVANTAGE - The fuel cell membrane has high performance, and long service life.    DETAILED DESCRIPTION - High tolerance fuel cell membrane formed by a perfluoro ion exchange resin, comprises at least one of degradable oxygen-derived free radical additive. The perfluoro ion exchange resin is at least one of perfluorosulfonic acid resin and perfluorophosphoric acid resin, perfluorosulfonic acid-perfluorophosphoric acid copolymer resin. The free radical additive is at least one of 3-(3,4-dihydroxyphenyl)acrylaldehyde compound of formula (VI), 4,6-dihydroxy quinoline or derivatives of formula (VII), quinolinyl-boronic acid compound of formula (VIII), isoquinolinyl boronic acid compound of formula (IX), and metal complexes of compounds (VI)-(VIII), where the metal is tungsten, zirconium, iridium, yttrium, manganese, ruthenium, cerium, vanadium, zinc, titanium or lanthanum, preferably manganese, cerium, lanthanum or ruthenium.    R1, R4, R5 = OH, OCH3, OC2H5, 3,3'-bipyridinyl-5-oxy, 2,2',6',2''-terpyridin-4-oxy, 2,2',6',2''-terpyridin-4'-oxy or 1,10-phenanthrolin-5-yloxy; and    R2, R3 = H, CH3 or C2H5.    An INDEPENDENT CLAIM is also included for the fuel cell membrane, comprising dispersing perfluoro ion-exchange resin in a solvent to obtain a dispersion liquid, adding degradable oxygen-derived free radical additive to obtain a mixed solution, and (a) taking the mixed solution and film forming by solution casting, solution pouring, screen painting, spin coating, spray coating or dipping method on the bearer body, and volatilizing the solvent to obtain the product.
