20080318102 | Bipolar Plate for Fuel Cell Comprising a Connecting Channel - The invention concerns a bipolar plate for fuel cell, of the type comprising a cathode bipolar half-plate and an anode bipolar half-plate attached to each other, each bipolar half-plate ( | 12-25-2008 |
20090042074 | BIPOLAR PLATE FOR FUEL CELL, COMPRISING SEALING RIBS - The invention relates to a bipolar plate for a fuel cell, of the type that comprises a cathode bipolar half plate and an anode bipolar half plate which are placed next to one another. Each bipolar half plate ( | 02-12-2009 |
20090075154 | FUEL CELL BIPOLAR PLATE AND FUEL CELL WITH IMPROVED FLUID DISTRIBUTION EMPLOYING SUCH PLATES - A bipolar plate for a fuel cell including a first through-hole positioned within one of its peripheral edges for circulating a reactive fluid, an anode compartment extending at one of its two main faces, and a cathode compartment extending at the opposite main face. At least one of the compartments is formed completely or partially by a region recessed with respect to the corresponding main face. The recessed region is connected to the through-hole via an intake channel that is recessed within the peripheral edge of the corresponding main face for the reactive fluid to flow into the compartment. A second through-hole located near the first through-hole is provided and is intended for circulating the reactive fluid. The main face opposite the face housing the recessed region comprises a generally non-emergent groove that connects the first and second through-holes. | 03-19-2009 |
20090155670 | FUEL CELL WITH FLAT ASSEMBLY AND SIMPLIFIED SEALING - Flat fuel cell comprising at least two unit cells, a casing provided with supports for each of said unit cells, said supports offering a bearing surface to a periphery of the unit cells, sealing means interposed between the periphery of each unit cell and the surface of an associated support, and a cover forming a compression element coming into abutment on the periphery of each unit cell opposite the sealing means and cooperating directly with the associated support in order to provide compression of the sealing means. | 06-18-2009 |
20100098982 | MONOPOLAR FUEL CELL ENDPLATE AND FUEL CELL COMPRISING SAME - The invention concerns a monopolar fuel cell endplate ( | 04-22-2010 |
20100129725 | FUEL CELL BIPOLAR PLATE WITH INTEGRATED SEALING AND FUEL CELL COMPRISING SUCH PLATES - The invention relates to a fuel cell bipolar plate ( | 05-27-2010 |
20110189552 | DRAINING MEANS FOR A FUEL CELL SYSTEM AND RELATED ADJUSTMENT MODE - The invention relates to a draining device for a fuel cell (FC). The effluents from a hydrogen FC comprising a recirculation circuit have to be regularly drained in order to guarantee optimum operation. The draining devices of the prior art are characterized by significant variations in the hydrogen concentration of the effluents. The invention consists in incorporating the draining means in the device for separating the liquid and gas phases of the effluents. Advantageously, means for fine regulation of the draining flow rate are provided, which makes it possible to limit the losses of hydrogen the drained effluents. | 08-04-2011 |
20130302712 | FUEL-CELL STACK COMPRISING A STACK OF CELLS AND BIPOLAR CONDUCTIVE PLATES - A fuel-cell stack including a stack of fuel cells with intermediate conductive bipolar plates. The bipolar plates include internal flow channels for flow of a heat-transfer fluid. The channels are connected to a circuit of a cooling system. Only some of the bipolar plates include internal flow channels that are temporarily or permanently not in service. | 11-14-2013 |
