Beschreibung
Zusammenfassung:	The present invention relates to a metal separator for a fuel cell, and specifically, to a metal separator for a fuel cell including: a metal base material; a metal layer formed on the metal base material; and a carbon layer formed on the metal layer, wherein the carbon layer is doped with crystalline graphite inside a matrix of amorphous carbon. The separator for a fuel cell according to the present invention has good corrosion resistance and electrical conductivity, and maintains excellent fuel cell performance even during a long-term use. 본 발명은 연료전지용 금속 분리판에 관한 것으로써, 구체적으로는 금속 모재, 금속 모재의 위에 형성된 금속층 및 금속층의 위에 형성된 카본층을 포함하며, 카본층이 비정질 카본의 매트릭스 내부에 결정성을 갖는 흑연이 도핑 된다. 본 발명에 따른 연료전지용 분리판은 내부식성 및 전기전도성이 좋고, 장기 사용에도 우수한 연료전지 성능을 유지한다.
