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.

Abstract: A separator for a fuel cell and a method for manufacturing the same comprise two sheets of metal plates integrally formed to minimize contact resistance between an upper metal plate and a lower metal plate. The method for manufacturing the separator includes steps of preparing an upper metal plate and a lower metal plate, each plate having opposing main sides, and applying a coating liquid containing a polymer composite material on both sides of the upper and lower metal plates, to form first and second composite material layers on both sides of the upper plates and third and fourth composite material layers on both sides of the lower plates. The method further includes stacking the upper metal plate on the lower metal plate, before drying the respective composite material layers, and integrally bonding the second composite material layer and the third composite material layer to form a single intermediate composite material layer.

Abstract: A separator for a fuel cell includes a channel having a passage that is a flow path of a reaction gas, a manifold part formed at a peripheral of the channel and communicating with the passage such that the reaction gas is introduced into and discharged from the channel, and a connector connecting the channel and the manifold part such that the reaction gas flows between the channel and the manifold part. The manifold part includes an inlet manifold through which the reaction gas is introduced into the channel and formed at a lower portion of the channel, and an outlet manifold configured to discharge the reaction gas from the channel to an outside of the fuel cell and formed at an upper portion of the channel.
