To provide a solid polymer electrolyte composition that can improve oxidation resistance without causing decrease in proton conductivity, elution of added components and the like, and an ion-exchange membrane, a membrane electrode assembly and a fuel cell, each using the composition. It is possible to obtain a solid polymer electrolyte composition having excellent oxidation resistance without causing decrease in proton conductivity, elution of added components and the like, by mixing an aromatic hydrocarbon-based polymer electrolyte, a phosphorus-containing polymer compound and a metallic element.
提供一种固体聚合物电解质组合物,该组合物能够提高抗氧化性,同时不会导致质子电导率下降、添加成分洗脱等问题,还提供了一种离子交换膜、膜电极组件和燃料电池,每一种都使用了该组合物。通过混合芳香烃基聚合物电解质、含磷聚合物化合物和金属元素,可以获得一种固体聚合物电解质组合物,该组合物具有优异的抗氧化性,同时不会导致质子传导性降低、添加成分洗脱等问题。
