Abstract
A metallic separator in which falling off of the conductive inclusions projecting from a matrix surface is prevented, whereby the contact resistance is decreased, resulting in increasing the characteristics for generation of electrical energy. A metallic separator for a fuel cell comprises conductive inclusions in a metal structure, and the conductive inclusions project from a surface of a matrix to a height of 1 to 3 micrometers.
