A polymer electrolyte membrane comprising a microporous polymer membrane having pores penetrating through the opposite sides thereof. The microporous polymer membrane holds a mixture of a polymer and a molten salt at a weight ratio of 1/99 to 99/1 and/or a molten salt. The polymer electrolyte membrane is inexpensive, durable, excellent in mechanical strength, excellent in structural retention in high temperatures, and capable of stably holding a molten salt in its porous polymer membrane structure, shows high heat resistance, and secures high ionic conductivity in the absence of water or a solvent and is therefore useful in fuel cells, secondary batteries, electric double layer capacitors, electrolytic capacitors, and the like.
一种聚合物电解质膜,包括具有贯穿其相对两侧的孔隙的微孔聚合物膜。微孔聚合物膜保持聚合物和熔盐的混合物,重量比为1/99至99/1和/或熔盐。聚合物电解质膜廉价、耐用、机械强度优异、在高温下具有良好的结构保持性,能够稳定地保持熔盐在其多孔聚合物膜结构中,具有高耐热性,且在无水或溶剂的情况下保持高离子导电性,因此在燃料电池、二次电池、电双层电容器、电解电容器等方面非常有用。
