Abstract: The invention provides composite membrane materials comprising a polymer of the state of art uniformly filled with a zirconium phosphate, preferably alpha-zirconium phosphate or zirconium phosphate sulfoarylenphosphonate particels. The composite membrane materials are preferably prepared starting from a solution of a polymer of the state of art and from a colloidal dispersion of alpha-zirconium phosphate or a zirconium phosphate sulfoarylenphosphonate. The colloidal particles are transferred into the solution of the polymer preferably by mixing the dispersion with the solution or by means of phase transfer. The membrane material is preferably obtained by removing the solvent by evaporation or by a suitable non-solvent. Besides the composite membrane materials and the preparation methods, the use of the above membrane materials is claimed as ionomeric membranes with high overall performance in high tempreature, especially hydrogen, and in indirect methanol fuel cells and with decreased methanol crossover in direct methanol fuel cells.

Abstract translation: 本发明提供了复合膜材料，其包含均匀填充有磷酸锆，优选α-磷酸锆或磷酸锆磺酸芳基膦酸盐颗粒的现有技术聚合物。 复合膜材料优选从现有技术的聚合物溶液和α-磷酸氢锆或磷酸锆磺酸芳基膦酸酯的胶态分散体开始制备。 优选通过将分散体与溶液混合或通过相转移将胶体颗粒转移到聚合物溶液中。 膜材料优选通过蒸发除去溶剂或通过合适的非溶剂来获得。 除了复合膜材料和制备方法之外，还要求使用上述膜材料作为在高温下尤其是氢气和间接甲醇燃料电池中具有高总体性能的离聚物膜，并且在直接甲醇燃料电池中具有降低的甲醇交叉。
