More Information
Summary:A fuel cell catalyst material includes metal catalyst particles made of a metal material, and a carbon-based coating composition at least partially coating at least some of the metal catalyst particles. The carbon-based coating composition includes a carbon network. The carbon-based coating composition is doped with a dopant. The carbon-based coating composition includes a plurality of defects formed by one or more escaped carbon atoms in the carbon network. 연료 전지 촉매 재료는, 금속 재료로 형성된 금속 촉매 입자, 및 상기 금속 촉매 입자들 중 적어도 일부를 적어도 부분적으로 코팅하는 탄소계 코팅 조성물을 포함한다. 상기 탄소계 코팅 조성물은 탄소 네트워크를 포함한다. 상기 탄소계 코팅 조성물은 도펀트로 도핑된다. 상기 탄소계 코팅 조성물은 상기 탄소 네트워크 내에 하나 이상의 이탈한 탄소 원자들에 의해 형성된 다수의 결함들을 포함한다.
