摘要： A process for reducing the amount of soluble polymeric fractions in a sulfonyl fluoride polymer. The process comprises contacting the sulfonyl fluoride polymer with a fluorinated fluid followed by separation of the polymer from the fluid. The fluorinated fluid is selected from hydrofluoroethers and hydrofluoropolyethers. The invention further relates to sulfonyl fluoride polymers obtainable by the process and having a heat of fusion not exceeding 4 J/g and containing less than 15% by weight of polymeric fractions having an average content of monomeric units comprising a sulfonyl functional group exceeding 24 mole %. The sulfonyl fluoride polymers so obtained are particularly suitable for the preparation of ionomeric membranes for use in electrochemical devices.

摘要： Described is a method for producing covalently and/or ionically cross-linked blend membranes from a halomethylated polymer, a polymer comprising tertiary N-basic groups, preferably polybenzimidazole, and, optionally, a polymer comprising cation exchanger groups such as sulfonic acid groups or phosphonic acid groups. The membranes can be tailor-made in respect of the properties thereof and are suitable, for example, for use as cation exchanger membranes or anion exchanger membranes in low-temperature fuel cells or low-temperature electrolysis or in redox flow batteries, or—when doped with proton conductors such as phosphoric acid or phosphonic acid—for use in medium-temperature fuel cells or medium-temperature electrolysis.

摘要： The present invention relates to a polymer electrolyte membrane, and a membrane-electrode assembly and a fuel cell containing the same, and the polymer electrolyte membrane comprises a polymer comprising repeating units represented by the following chemical formulas 1-3. Chemical formulas 1-3 are as defined in the specification. The polymer electrolyte membrane has excellent resistance to radical attack and has improved acid-base interaction, thereby maximizing the function of an ion conductive group, and thus can improve the operation performance of a fuel cell in a low humidification state.

摘要： An electrolyte membrane of a membrane-electrode assembly is formed by a manufacturing method yielding a membrane with improved chemical durability. The manufacturing method includes preparing an antioxidant solution, mixing the antioxidant solution and a first ionomer dispersion solution, drying the mixture to produce a composite having an antioxidant and a first ionomer surrounding the antioxidant, introducing and mixing the composite with a second ionomer dispersion solution, and applying that mixture to a substrate and drying the mixture to manufacture an electrolyte membrane. The resulting electrolyte membrane includes the composite having an antioxidant in an ionic state and a first ionomer surrounding the antioxidant.
