Abstract: PURPOSE: A manufacturing method of a nano structure metal carbide and the and nano structure metal carbide manufactured from thereof are provided to perform a pressing molding and a sintering operation at high temperature in several minutes by heating nano powder with a heat generated from an inducing current or an impulse current. CONSTITUTION: A manufacturing method of a nano structure metal carbide comprises the following steps: nano pulverizing the metal carbide powder to make a nano particle size by ball milling; pressing molding and sintering the powder from the nano pulverizing step while heating the powder with a heat generated from an electric current; and cooling the pressing molded and sintered nano structure at room temperature when the contraction length does not change by blocking the electric current. The metal carbide powder is selected from the group consisting of titanium carbide, tungsten carbide, silicon carbide, tantalium carbide, vanadium carbide, and niobium carbide.

Abstract: PURPOSE: A fuel cell separator is provided to have mechanical properties similar to austenite-based stainless steel by using a metal material which is formed by minimally using expensive metal elements such as nickel, chrome, etc., and to have long-term stable durability while ensuring the performance of a fuel cell. CONSTITUTION: A fuel cell separator comprises a stainless steel sheet material, and a passivation layer which comprises titanium-aluminum-chrome nitride formed on the sheet material. The passivation layer consists of 10-13 wt% of titanium, 10-13 wt% of aluminum, 50-54 wt% of chrome, and 20-30 wt% of nitrogen. The thickness of the passivation layer is 3-30. The passivation layer is obtained by depositing titanium, aluminum and chrome specimen on the stainless steel sheet material through an ion plasma sputtering method in a nitrogen gas atmosphere.

Abstract: PURPOSE: A manufacturing method of a fuel cell separator is provided to economically manufacture a fuel cell separator with long term-stable durability by forming a stable passivation layer on a metal material separator. CONSTITUTION: A manufacturing method of a fuel cell separator comprises: a step of forming a passivation layer, which comprises titanium-aluminum-chrome nitride on a stainless steel plate material. In here, the passivation layer is formed by ion plasma sputtering titanium, aluminum and chrome specimen in a nitrogen gas atmosphere. The thickness of the passivation layer is 3-30. In the ion plasma sputtering, current applied to the titanium, aluminum and chrome specimen is independently controlled.
