高分子電解質および該高分子電解質を用いた膜電極接合体ならびに燃料電池
Document Type and Number:
Japanese Patent JP5870495
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an electrolyte cross-linked without reducing ion exchange capacity, exhibiting high proton conductivity in a low humidification condition, and excellent in water resistance, and a membrane electrode assembly and a fuel cell including the polymer electrolyte, at low cost.SOLUTION: A cross-linked polymer electrolyte is formed using a cross-linked polymer as main constituents, the cross-linked polymer being obtained by reacting a proton conductive polymer, which has a constitutional unit represented by the following formula, with a crosslinking agent. (Y represents a proton acid group selected from among a sulfonic acid group, a phosphonic acid group, a hydroxyl group and a carboxyl group, and k represents an integer of 1-4.)
