Title:
高分子電解質膜、膜−電極接合体、及び固体高分子型燃料電池
Document Type and Number:
Japanese Patent JP5706906
Kind Code:
B2
Abstract:
Provided are: a polymer electrolyte membrane that is highly resistant to hot water and has high ion conductivity and excellent electricity-generation performance; a membrane-electrode assembly provided with said polymer electrolyte membrane and electrodes; and a polymer electrolyte fuel cell provided with the aforementioned polymer electrolyte membrane. Namely: a polymer electrolyte membrane that contains a block copolymer comprising an ion-conducting polymer block (A) and a non-ion-conducting polymer block (B), said polymer electrolyte membrane being characterized in that said non-ion-conducting polymer block (B) is obtained by cross-linking by means of a non-polar cross-linker (X); a membrane-electrode assembly provided with said polymer electrolyte membrane and gas diffusion electrodes; and a polymer electrolyte fuel cell provided with the aforementioned polymer electrolyte membrane.
