Publication number: 20250158082Abstract: A method of manufacturing a fuel cell catalyst can include a method of manufacturing a carbon carrier for a fuel cell catalyst, in which the carbon carrier can have an improved binding force to a catalytic metal and improved carbon durability. The carbon carrier can be coated with a carbon layer highly doped with heteroatoms. The carbon layer can be formed by uniformly compounding a conductive polymer containing the heteroatoms with the carbon carrier and heat-treating the compounded mixture.Type: ApplicationFiled: June 21, 2024Publication date: May 15, 2025Inventors: Young Jung Heo, Hee Su Yang
