The present invention relates to a separator for a fuel cell, a method for manufacturing the same, and a fuel cell system manufactured therefrom, and more particularly, to a separator for a fuel cell including nanographite flakes having a thickness of 3 to 30 nm in a resin. And a method for manufacturing the same and a fuel cell system manufactured therefrom.n n n In the fuel cell separator of the present invention, since nano graphite flakes having a thickness of nanometers are included in the resin, sufficient electrical conductivity can be obtained even with a small amount of graphite, so that the weight can be reduced, and the bonding force between the resin and the graphite increases. It has excellent mechanical properties and durability, and has excellent heat stability due to the reduction of the coefficient of thermal expansion. |
