20120231372 | METALLIC BIPOLAR PLATE FOR FUEL CELL AND METHOD FOR FORMING SURFACE LAYER THEREOF - A metallic bipolar plate for a fuel cell, in which a carbon coating layer containing fluorine is formed on the surface of a stainless steel base material, thus having excellent electrical conductivity and corrosion resistance and further excellent water draining performance and heat radiating performance. In the metallic bipolar plate for a fuel cell of the present invention, the internal residual stress in the surface coating layer is significantly reduced due to the addition of fluorine, and thereby it is possible to improve the adhesive strength between the stainless steel and the surface coating layer. | 09-13-2012 |
20120297851 | METHOD AND APPARATUS FOR MANUFACTURING PANELS FOR VEHICLES - Disclosed herein is a method and apparatus for manufacturing a panel for a vehicle. When a steel sheet is machined to form a panel for a vehicle, a blanking-texturing machine conducts a blanking process for cutting the steel sheet and a texturing process for forming depressions in the steel sheet at the same time. Therefore, the present invention reduces the number of manufacturing processes, thus enhancing the productivity, and reducing the production cost and provides a steel sheet with uniform depressions across the surface of the steel sheet, thereby reducing the coefficient of friction during the pressing process consistently. | 11-29-2012 |
