  Provided are a hydroxyl group-containing sulfonated polyethersulfone copolymer, a method for preparing the same, a polymer electrolyte membrane for fuel cell, and a membrane electrode assembly including the same. More particularly, provided are a hydroxyl group-containing sulfonated polyethersulfone electrolyte membrane and a membrane electrode assembly including the same, which are applied to a fuel cell to provide significantly higher ion conductivity as compared to the sulfonated polymer electrolyte membranes according to the related art. The hydroxyl group-containing sulfonated polyethersulfone copolymer electrolyte membrane shows significantly higher ion conductivity under various temperature and humidity conditions as compared to the sulfonated polymer electrolyte membranes according to the related art. Therefore, it is expected that the hydroxyl group-containing sulfonated polyethersulfone copolymer substitutes for expensive fluoropolymer electrolyte membranes such as Nafion.

  本发明提供了一种含羟基的磺化聚醚砜共聚物、其制备方法、一种燃料电池用聚合物电解质膜以及包括其在内的膜电极组件。更具体地说，本发明提供了一种含羟基的磺化聚醚砜电解质膜和包括其在内的膜电极组件，与相关技术中的磺化聚合物电解质膜相比，将其应用于燃料电池可显著提高离子传导性。与相关技术中的磺化聚合物电解质膜相比，含羟基的磺化聚醚砜共聚物电解质膜在各种温度和湿度条件下的离子传导性明显更高。因此，含羟基的磺化聚醚砜共聚物有望取代昂贵的含氟聚合物电解质膜（如 Nafion）。
