| 20090191444 | FUEL CELL BIPOLAR PLATE AND METHOD FOR PRODUCING THE SAME - Certain embodiments provide a bipolar plate for a fuel cell having a novel configuration in which the draining function is improved, the operation is simplified, the resin contained therein is prevented from being decomposed and eluted, and methods for producing the same. The methods for producing a bipolar plate for a fuel cell comprised of a composite material of carbon powders and a thermosetting resin generally comprise the steps of compressing said composite material of the carbon powders and the thermosetting resin by compression molding to provide a molded body having a gas flow field groove for flowing a reactive gas formed on at least one of the surfaces thereof, wherein a punching die and a molding die opposed to each other are used and said composite material of the carbon powders and the thermosetting resin are received in a material receiving part of said molding die, wherein said punching die is approached relative to said molding die; and irradiating an infrared laser beam toward the internal surface of said gas flow field groove while moving the optical axis of said infrared laser beam relatively to said molded body along said gas flow field groove, thereby applying infrared laser process to said internal surface of said gas flow field groove after the completion of said compressing step. | 07-30-2009 |
| 20090117441 | Molding Die for Fuel Cell Bipolar Plate, Manufacturing Method of Fuel Cell Bipolar Plate, and Fuel Cell Bipolar Plate - To obtain a fuel cell bipolar plate of high quality and high productivity with less deformation, warpage, and cracking at the time of product removal from a die by making equal the density balance between a gas flow passage groove part area and a surrounding part area on the surface of the bipolar plate. | 05-07-2009 |
| 20090117315 | Disc-molding mold, mirror-surface disc, and method for producing mold for disc molding - An object is to improve the durability of a mold and reduce the cost of the mold. A disc-molding mold includes a first mold; and a second mold disposed in opposition to the first mold such that the second mold can advance and retreat. One of the first and second molds includes a base material having a roughened surface, and a coating layer formed on the surface of the base material through coating treatment. A stamper attachment surface is defined on a surface of the coating layer. Since a coating layer is formed on the roughened surface of the base material through coating treatment, the area of contact between the base material and the coating layer can be increased. Therefore, the adhesion force between the base material and the coating layer increases, so that the coating layer becomes unlikely to peel off, whereby the durability of the mold can be improved, and the cost of the mold can be reduced. | 05-07-2009 |
