摘要： A polysulfone is provided with a nitrogen-containing functional group having an affinity to an acid, an electrolyte membrane using the polysulfone, and a fuel cell including the electrolyte membrane. In particular, the polysulfone includes a nitrogen-containing functional group that has an affinity to an acid, such as a phosphoric acid, thereby having an excellent acid retaining ability. In an electrolyte membrane including the polysulfone and an acid, the amount of the retained acid can be controlled. Therefore, the electrolyte membrane has a high ionic conductivity and a high mechanical strength. A polysulfone blend of polysulfone and a thermoplastic resin prevents the dissolution of polysulfone by phosphoric acid, so that an electrolyte membrane using the polysulfone blend has an improved durability. A cross-linked reaction product of polysulfone, a cross-linking agent and a polymerization product of polysulfone, a thermoplastic resin, and a cross-linking agent strongly resist a phosphoric acid. Thus, a fuel cell using these polymerization products has a long lifetime and can operate at a high temperature and at a high efficiency.
摘要翻译：聚砜具有对酸具有亲和性的含氮官能团，使用聚砜的电解质膜和包含电解质膜的燃料电池。特别地，聚砜包括与酸如磷酸具有亲和性的含氮官能团，因此具有优异的酸保留能力。在包含聚砜和酸的电解质膜中，可以控制保留的酸的量。因此，电解质膜具有高离子传导性和高机械强度。聚砜和热塑性树脂的聚砜共混物防止磷酸溶解聚砜，使得使用聚砜共混物的电解质膜具有改善的耐久性。聚砜，交联剂和聚砜，热塑性树脂和交联剂的聚合产物的交联反应产物强烈地抵抗磷酸。因此，使用这些聚合产物的燃料电池具有长的使用寿命并且可以在高温和高效率下运行。
