Zusammenfassung:	The present invention relates to a separation plate for a fuel cell and more specifically, relates to the separation plate for the fuel cell with excellent corrosion resistance and conductivity having a ratio of a structure of a specific carbon coating layer and a specific metal oxide film, and a coating method of the separation plate for the fuel cell. The separation plate for the fuel cell according to the present invention comprises a metal base material and a carbon coating layer formed on a surface of the metal base material and made of a carbon domain of a size of 15-30 nm. 연료 전지용 분리판에 관한 것으로, 보다 상세하게는, 특정한 탄소 코팅층 의 구조와 특정한 금속 산화막의 비율을 갖는 내식성 및 전도성이 우수한 연료 전지용 분리판 및 연료 전지용 분리판의 코팅 방법에 관한 것이다. 본 발명에 따른 연료 전지용 분리판은 금속 모재 및 상기 금속 모재의 표면 상에 형성되고, 15 ~ 30nm 크기의 탄소 도메인으로 이루어진 탄소 코팅층을 포함한다.
