摘要： A bipolar plate for a fuel cell includes a metal plate and a coating layer disposed on a surface of the metal plate. The coating layer includes a polymer of an oxazine-based compound, particularly, a benzoxazine-based compound and a conducting material. A method of manufacturing the bipolar plate includes coating a surface of a metal plate with a coating layer forming composition including at least one oxazine-based compound, a conducting material, and a solvent; and thermally treating the metal plate coated with the coating layer forming composition. A fuel cell includes the bipolar plate.
