Title:
ELECTROLYTE MEMBRANE, METHOD OF MANUFACTURING THE SAME, AND MEMBRANE-ELECTRODE ASSEMBLY FOR FUEL CELL EQUIPPED WITH ELECTROLYTE MEMBRANE
Document Type and Number:
Japanese Patent JP2017107805
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an electrolyte membrane capable of playing a role as a diaphragm even when decomposition reaction due to a peroxide occurs.SOLUTION: Disclosed is an electrolyte membrane having a phase A constituting a matrix phase and a phase B. The phase B exists continuously from a first main surface of the electrolyte membrane to a second main surface on the side opposite to the first main surface. The phase B contains a graft polymer having a main chain and a graft chain. The graft chain has a functional group having anion exchange ability. The main chain is preferable not to have the functional group having the anion exchange ability.SELECTED DRAWING: Figure 1
