Title:
METHOD FOR MANUFACTURING FUEL CELL CATALYST ELECTRODE HAVING NANOPOROUS STRUCTURE, AND FUEL CELL CATALYST ELECTRODE MANUFACTURED THEREBY
Document Type and Number:
WIPO Patent Application WO/2017/047957
Kind Code:
A1
Abstract:
One embodiment of the present invention provides: a method for manufacturing a fuel cell catalyst electrode, the method forming a catalyst layer of the catalyst electrode into a nanoporous structure by deposition so as to make a process simple and efficient; and a fuel cell catalyst electrode manufactured thereby. The method for manufacturing a fuel cell catalyst electrode having the nanoporous structure, according to an embodiment of the present invention, comprises: a step of preparing a membrane for a polymer electrolyte membrane fuel cell (PEMFC); a step of fixing the membrane to a deposition chamber; vacuuming the inside of the deposition chamber; a step of injecting a process gas into the vacuumed deposition chamber such that the process gas forms an initial process pressure; a step of setting the temperature of the membrane to 50°C or lower; a step of raising, as a deposition step, the temperature of an evaporation source having a deposition material contained therein, so as to form steam of the deposition material; and a step of allowing the generated deposition particles to form a catalyst layer on one surface of the membrane.
