Currently, Carbon Black(Vulcan XC-72) is used to Fuel Cell catalysts and has advantageous properties such as high conductivity, oxidation resistance and large surface area, etc., But, it has a surface treatment process cause of low dispersibility in the substrate. In this study, provide functional groups on the surface of Carbon Black by eco-friendly organic acid and fuel cell catalysts were created by dispersed platinum particles. In addition, electrochemical properties of the carbon black-supported were analyzed by CV. Through a variety of temperature and composition of the organic acid, catalyst can improve the dispersion.
