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.

Coating method of separator for fuel cell and separator for fuel cell

A fuel cell separator includes a metal substrate having a surface; an ion penetration layer including carbon diffusion-inhibiting ions extending from the surface of the metal substrate into the metal substrate; and a carbon coating layer disposed on the surface of the metal substrate.

Fuel cell separator and coating method for fuel cell separator

A separator for a fuel cell includes: a metal base material; and a carbon coating layer formed on one surface or both surfaces of the metal base material, in which roughness Ra formed at an interface between the metal base material and the carbon coating layer may be in a range of 20 to 78 nm.
