ELECTRODE BINDER, ELECTRODE, MEMBRANE-ELECTRODE ASSEMBLY, AND SOLID POLYMER FUEL CELL

摘要

Disclosed is an electrode which can be used in a fuel cell having improved power generation performance and high durability. Also disclosed is a fuel cell comprising such an electrode. Specifically disclosed is an electrode to be used in a fuel cell, which has catalyst layers arranged on both sides of an electrolyte membrane. This electrode is characterized in that an electrode binder used for constituting the catalyst layers contains a crosslinkable compound (X) having a silicon-oxygen bond, a polymer material (Y) containing an acid group, and an aqueous dispersion (Z) containing a thermoplastic resin.
