ELECTRODE CATALYST BINDER FOR SOLID POLYMER FUEL CELLS

Title:

ELECTRODE CATALYST BINDER FOR SOLID POLYMER FUEL CELLS

Document Type and Number:

WIPO Patent Application WO/2016/076129

Kind Code:

A1

Abstract:

This electrode catalyst binder for solid polymer fuel cells contains a polymer compound that has a repeating unit represented by formula (1). This electrode catalyst binder enables a solid polymer fuel cell to have high power generation efficiency, especially in cases where this electrode catalyst binder is used for a cathode-side electrode of the solid polymer fuel cell. A-Y-CH(SO2Rf)2 (1) (In the formula, A is a group that represents the main chain structure of the polymer compound; Y is a group that represents a divalent organic group; and each Rf independently represents a perfluoroalkyl group having 1-4 carbon atoms.)
