ELECTRODE FOR FUEL CELL AND METHOD FOR MANUFACTURING SAME, MEMBRANE ELECTRODE ASSEMBLY, AND SOLID POLYMER FUEL CELL

WIPO Patent Application WO/2015/002287

A1

　Provided is a method for manufacturing an electrode for a fuel cell having excellent durability against electrochemical oxidation and having an electronically conductive oxide that has excellent output characteristics used therefor. An electrode for a fuel cell having a gas diffusion layer, which is electronically conductive, and an electrode catalyst layer formed on the surface of or inside the gas diffusion layer, wherein the electrode for a fuel cell is characterized in that the electrode catalyst layer contains an electronically conductive oxide layer having a gas diffusion property formed by physical vapor deposition and electron catalyst particles carried by the electronically conductive oxide layer. In the electrode for a fuel cell, the electronically conductive oxide particles constituting the electronically conductive oxide layer in the electrode catalyst layer are connected particles in which a plurality of particles are linked. Therefore, electrical resistance caused by grain boundaries is reduced and excellent electron conductivity is obtained in the electrode as a whole.
