| 20090117416 | End plates for fuel cell stack and method of manufacturing the same - The present invention provides an end plate for a fuel cell stack and a method of manufacturing the same, in which the end plate connected to each of both ends of a fuel cell stack is manufactured in a hybrid structure using two kinds of materials having different coefficients of thermal expansion, thus providing a uniform surface pressure in the fuel cell stack. | 05-07-2009 |
| 20090269671 | Fuel cell separator and method for manufacturing the same - The present invention provides a fuel cell separator formed of a continuous carbon-fiber composite, and a method for manufacturing the same. | 10-29-2009 |
| 20090286134 | END PLATE FOR FUEL CELL STACK AND METHOD FOR MANUFACTURING THE SAME - The present invention provides an end plate for fuel cell stack and a method for manufacturing an end plate, which can increase flexural rigidity per weight, and improve strain at break, and reduce heat transmission by applying hybrid core element having honeycomb and form structures to an end plate having sandwich structure combined to both end portions of a fuel cell stack. | 11-19-2009 |
| 20090311566 | SEPARATING PLATE FOR FUEL CELL STACK AND METHOD OF MANUFACTURING THE SAME - The present invention provides a separating plate for a fuel cell stack and method of manufacturing the same, and more particularly, to a separating plate for a fuel cell stack and method of manufacturing the same, in which the separating plate constituting the fuel cell stack is formed in such a fashion as to interpose an array of metal pipes between two sheets of composite material, and a gasket abutting against the separating plate is formed in such a fashion as to define hydrogen and air flow channels, thereby removing a contact resistance between two adjoining separating plates constituting unit cells to improve the efficiency of the fuel cell. | 12-17-2009 |
| 20110086292 | JOINING DEVICE FOR FUEL CELL STACK AND FUEL CELL STACK PROVIDED WITH THE SAME - The present invention features a fuel cell stack that preferably includes an electricity generating assembly having a plurality of unit cells that are suitably disposed one after another; a pair of end plates pressedly disposed respectively at upper and lower ends of the electricity generating assembly; and a joining device suitably engaging the end plates by a rope, where pressure is applied to the electricity generating assembly by means of tension of the rope, and the length and tension of the rope is suitably controlled. | 04-14-2011 |
| 20110123882 | SURFACE PRESSURE CONTROLLING DEVICE FOR FUEL CELL STACK - The present invention provides a surface pressure controlling device for a fuel cell stack, in which an inflator capable of being expanded by pneumatic or hydraulic pressure is mounted in an end plate so as to control the surface pressure required for the assembly of the fuel cell stack to be maintained above a predetermined level. | 05-26-2011 |
| 20110129737 | COMPOSITE SEPARATOR FOR POLYMER ELECTROLYTE MEMBRANE FUEL CELL AND METHOD FOR MANUFACTURING THE SAME - The present invention provides a composite separator for a polymer electrolyte membrane fuel cell (PEMFC) and a method for manufacturing the same, in which a graphite foil prepared by compressing expanded graphite is stacked on a carbon fiber-reinforced composite prepreg or a mixed solution prepared by mixing graphite flake and powder with a resin solvent is applied to the cured composite prepreg such that a graphite layer is integrally molded on the outermost end of the separator. | 06-02-2011 |
