    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.

    摘要： The present invention relates to a separator plate for a fuel cell and to a method for producing the same, and relates to an invention wherein a surface-modification layer is formed through the use of low temperature plasma processing such that it is possible to prevent the hydrophobic characteristics which occur during gasket forming and to have outstanding hydrophilic characteristics, and such that it is possible to obtain the advantageous effect of highly outstanding corrosion resistance and electrical conductivity not only initially but also even after long-term use in a fuel-cell operating environment, and also such that it is possible to maintain outstanding durability even when using a normal low-price stainless-steel sheet base material, and it is possible to reduce the unit cost of production of the separator plate for the fuel cell since surface processing can be carried out at low cost.

    摘要： Disclosed herein is a method for manufacturing a metal steel separator for fuel cells that has corrosion resistance and contact resistance not only at an initial stage but also after being exposed to high temperature/high humidity conditions in the fuel cell for a long period of time. The method includes preparing a stainless steel sheet as a matrix of the metal separator, forming a discontinuous coating film on the surface of the stainless steel sheet, the coating film being composed of at least one selected from gold (Au), platinum (Pt), ruthenium (Ru), iridium (Ir), ruthenium oxide (RuO2), and iridium oxide (IrO2), and heat treating the stainless steel sheet having the discontinuous coating film to form an oxide film on a portion of the stainless steel sheet on which the coating film is not formed. A metal separator for fuel cells manufactured by the method is also disclosed.
