PRE-COATING OF METAL BIPOLAR PLATE, METHOD OF FORMING THE SAME, METAL BIPOLAR PLATE PRODUCED BY USING THE SAME AND METHOD OF PRODUCING THE SAME

A pre-coating of a metal bipolar plate and a method of forming the same are provided. The pre-coating of the metal bipolar plate is used to form on a surface of a metal substrate. The pre-coating of the metal bipolar plate includes an intermediate layer disposed on the metal substrate, in which the intermediate layer includes transition metal carbide; and a surface conductive layer disposed on the intermediate layer, in which the surface conductive layer includes a graphite layer, and a thickness of the surface conductive layer is in a range of 0.2 μm to 1.0 μm. The pre-coating of the metal bipolar plate can have improved corrosion resistance and electrical conductivity, thereby being applied to the metal bipolar plate and the method of producing the same.
