CROSSLINKED ELECTROLYTE MEMBRANE FOR FUEL CELL

摘要

PROBLEM TO BE SOLVED: To improve the properties of conventional polymer electrolyte membrane such as the swelling suppressing ability and durability.

SOLUTION: The electrolyte membrane for fuel cell is produced by reacting a cation exchange membrane with a crosslinking agent expressed by chemical formula (1): I-(CH2)n-I (X is H or F; and n is 1-10). The electrolyte membrane for fuel cell has excellent antiacid property and methanol permeation inhibiting property attained by crosslinking.
