Abstract
Disclosed are a metal separator for fuel cells, which exhibits excellent properties in terms of corrosion resistance, electrical conductivity and durability, and a method of manufacturing the same. The metal separator for fuel cells includes a separator-shaped metal matrix and a coating layer formed on the metal matrix. The coating layer has a concentration gradient of a carbon element C and a metal element Me according to a thickness thereof such that the carbon element C becomes gradually concentrated in the coating layer with increasing distance from the metal matrix, and the metal element Me becomes gradually concentrated in the coating layer with decreasing distance from the metal matrix.
