Abstract: An object of the present invention is to provide a method of producing an electrode catalyst having excellent catalytic activity and excellent durability in an electrode catalyst layer of MEA for a PEFC. The method of producing an electrode catalyst having a porous carbon support that has nanopores having a pore diameter of 1 to 20 nm and a BET specific surface area of 700 to 900 m 2 /g, and catalyst particles containing Pt supported on the support, includes: a first step for preparing a powder in which the catalyst particles are supported on the support; and a second step for accommodating the powder obtained through the first step in a flow-type reactor, flowing NH 3 gas through the reactor under conditions of a concentration of 10 to 100% and a pressure of 0.1 MPa to 0.5 MPa, and regulating the temperature in the reactor to 500 °C or more and less than the decomposition temperature of ammonia, keeping for 5 to 10 hours to chemically react the powder and the NH 3 gas.

Abstract: Disclosed are: a membrane-electrode assembly having enhanced adhesion and interfacial durability between a polymer electrolyte membrane and electrodes; and a method for manufacturing a membrane-electrode assembly, in which, in forming electrodes by directly coating a catalyst slurry on a polymer electrolyte membrane, adhesion and interfacial durability between the polymer electrolyte membrane and the electrodes can be enhanced without a separate additional step, thus improving both the durability and the productivity of the membrane-electrode assembly. The method comprises the steps of: dispersing a catalyst and an ion conductor in a dispersion medium to obtain a catalyst slurry; applying the catalyst slurry onto a polymer electrolyte membrane; and drying the catalyst slurry applied onto the polymer electrolyte membrane to form an electrode. The dispersion medium is a solvent capable of forming a plurality of grooves on a surface of the polymer electrolyte membrane, and, when the electrode is formed through the drying step, at least some of the grooves are filled with the catalyst, the ion conductor, or a mixture thereof.

Abstract: The present invention relates to a catalyst layer for a fuel cell, a method for producing the catalyst layer, and a membrane-electrode assembly and a fuel cell including the catalyst layer. More particularly, the invention relates to a catalyst layer for a fuel cell, the catalyst layer including a catalyst, a heat dissipation material, and an ionomer and having an effect that the heat generated by an exothermic reaction in the catalyst layer can be efficiently discharged to the outside and a phenomenon of deterioration of a membrane-electrode assembly caused by temperature increase in the catalyst layer can be suppressed; a method for producing the catalyst layer; and a membrane-electrode assembly and a fuel cell, both including the catalyst layer.
