METAL SEPARATOR FOR FUEL CELL AND METHOD FOR TREATMENTING SURFACE OF THE SAME

摘要

PURPOSE: A surface treating method of a separator for a fuel cell is provided to form a micro protrusion providing hydrophobicity by attaching ionized nano particles to the surface of a separator by using high voltage derived from interrupted current. CONSTITUTION: A surface treating method of a separator for a fuel cell comprises: a step of offering nanoparticles for forming micro protrusion on a separator(11) to a discharge electrode(13); a step of ionizing the nanoparticles by arc discharging derived to the discharging electrode; a step of attaching the derived nanoparticles to the surface of the separator by applying high voltage between the separator and the discharge electrode; and a step of forming micro protrusions for obtaining hydrophobicity by stacking the nano particles on the surface of the separator.
