PURPOSE: A separator for a fuel cell using a conductive polymer is provided to prevent corrosion of metal, to increase power density, and to reduce contact resistance generated when coating composite materials. CONSTITUTION: A separator for a fuel cell comprises a substrate(200), a carbon nanotube layer(250) installed on whole surface of the substrate, and a composite layer(280) containing a mixture(260) of conductive additive and a polymer at the upper part of the carbon nanotube layer. The substrate comprises an air or hydrogen gas channel of uneven shape which is formed at the first side of a metal plate material; and a coolant channel of uneven shape which is formed at the second side of a metal plate material. |
