发明名称 METAL SEPARATOR PLATE FOR A FUEL CELL HAVING A COATING LAYER COMPRISING CARBON PARTICLES DISPERSED IN A BINDER RESIN, AND A PRODUCTION METHOD THEREFOR
摘要 Disclosed herein is a method of manufacturing a metallic bipolar plate for fuel cells, which can maintain good corrosion resistance and contact resistance without any side effect not only initially but also after a predetermined period of time even in an environment of severe vibration as in vehicles while allowing a continuous process to provide high productivity. The method includes (a) preparing a metal plate as a matrix of the metallic bipolar plate; (b) pickling a surface of the metal plate; (c) coating a composition comprising a binder resin, carbon particles, and a solvent on the pickled surface of the metal plate; and (d) drying the surface of the metal plate, on which the composition is coated, at a temperature less than a thermal decomposition temperature of the binder resin and greater than or equal to a boiling point of the solvent to form a coating layer on the surface of the metal plate, the coating layer having the carbon particles dispersed in a matrix of the binder resin, wherein these processes are performed as a continuous process.
