SURFACE MODIFIED MATERIAL, SULFONIMIDE COMPOUND FOR SURFACE MODIFICATION, AND FUEL CELL

摘要

PROBLEM TO BE SOLVED: To provide a surface modified material modified by sulfonimide compound group whose surface has high oxygen permeation and high proton conductivity, a fuel cell whose catalyst layer uses the surface modified material, and sulfonimide compound for manufacturing the surface modified material.

SOLUTION: The surface modified material includes base material and one or more kinds of sulfonimide compound groups bonded onto the surface of the base material via one or more linking groups -A-Y'- (A is a direct bond or organic group, and Y' is a bonding site with the base material) while the sulfonimide compound group has one or more linking groups -A-Y'- and two or more sulfonimide groups in a molecular structure. The fuel cell uses it for a catalyst layer. The sulfonimide compound for surface modified includes one or more reactive end groups -A-Y (A is a direct bond or organic group, and Y is a reactive functional group) and two or more sulfonimide groups.
