Abstract
The method for coating a separator for a fuel cell according to one form of the present disclosure includes the steps of: vaporizing a metal nitride precursor to obtain a precursor gas; introducing a metal nitride coating layer-forming gas containing the precursor gas and a reactive gas to a reaction chamber; applying a voltage to the reaction chamber so that the precursor gas and reactive gas may be converted into a plasma state, thereby forming a metal nitride coating layer on a substrate; introducing a carbon layer-forming gas containing a carbonaceous gas to the reaction chamber; and applying a voltage to the reaction chamber so that the carbonaceous gas may be converted into a plasma state, thereby forming a carbon coating layer on the metal nitride coating layer.
