FUEL CELL BIPOLAR PLATE BY NIO-YSZ SOL-GEL COATING, MANUFACTURING METHOD THEREOF, AND FUEL CELL USING THE SAME |
摘要 |
PURPOSE: A manufacturing method of a fuel cell separator is provided to improve corrosion resistance, electric conductivity, and strength of a fuel cell separator by uniformly coating an oxide nickel-including yttria-stabilized zirconia on the surface of a stainless steel separator. CONSTITUTION: A manufacturing method of a fuel cell separator comprises a step of manufacturing a sol-gel solution by dissolving a nickel precursor, yttrium precursor, and zirconium precursor into a solvent; a step of dip-coating the stainless steel with the sol-gel solution; and a step of heat-treating the stainless steel. The separator is coated with a NiO-YSZ layer. The thickness of the coating layer is 0.1-1 micron. The content of Ni is 5-25 wt% based on the total weight of the NiO-YSZ coating layer. |
