More Information
Summary:The present invention relates to mesoporous carbon, which is provided with a bead string structure including interconnected primary particles having mesopores, and has an average primary particle diameter of 7-300 nm, a pore diameter of 2-10 nm, an average pore wall thickness of 3-15 nm, a pore volume of 0.2-3.0 mL/g, and a tap density of 0.03-0.3 g/cm^3. The present invention also relates to a solid polymer electrolyte fuel cell including a cathode catalyst layer having a catalyst support using the mesoporous carbon. The mesoporous carbon is obtained by impregnating mesoporous silica satisfying a predetermined condition with a carbon source, carrying out polymerization and carbonization, and removing a template. 메소 다공 카본은, 메소 세공을 갖는 1차 입자가 연결되어 있는 연주 구조를 구비하고, 평균 1차 입자 직경이 7nm 이상 300nm 이하이고, 세공 직경이 2nm 이상 10nm 이하이고, 세공벽의 평균 두께가 3nm 이상 15nm 이하이고, 세공 용량이 0.2mL/g 이상 3.0mL/g 이하이고, 탭 밀도가 0.03g/cm3 이상 0.3g/cm3 이하인 것을 포함한다. 고체 고분자형 연료 전지는, 이러한 메소 다공 카본을 적어도 공기극 촉매층의 촉매 담체에 사용한 것을 포함한다. 이러한 메소 다공 카본은, 소정의 조건을 충족하는 메소 다공 실리카에 탄소원을 함침, 중합 및 탄화시켜, 주형을 제거함으로써 얻어진다.
