The cell unit for a fuel cell can include an electrolyte membrane; an electrode unit, comprising an anode being formed on one surface of the electrolyte membrane and a cathode being formed on the other surface of the electrolyte membrane; a current collector, being stacked on the electrode unit to be electrically connected to the electrode unit; and a conductive layer, being interposed between the electrode unit and the current collector to reduce a contact resistance between the electrode unit and the current collector. With the present invention, the cell unit for a fuel cell can reduce contact resistance between the anode and the cathode and the current collector. Accordingly, it can be possible to reduce the overall size of the fuel cell by reducing the required thickness of the end plate. | 11-19-2009 |
| 20090305108 | Fuel Cell Device - A surface on the fuel electrode side of a lower portion of a separator in a fuel cell stack is made to have water repellency, so that water accumulated in a fuel gas flow path can be appropriately discharged, and thus so that reduction in fuel cell performance and deterioration of the fuel electrode can be surely prevented. For that purpose, in a fuel cell device, a fuel cell having an electrolyte layer interposed between the fuel electrode and an oxygen electrode includes a cell module laminated so as to interpose a separator formed with the fuel gas flow path along the fuel electrode, and a fuel gas flows substantially perpendicularly to the direction of gravity in the fuel gas flow path. The separator is provided with a water-repellent surface on the fuel electrode side of a lower portion thereof. | 12-10-2009 |
| 20090305109 | Fuel Cell Device - A portion of a fuel electrode corresponding to a portion in a fuel gas flow path where water accumulates is made to contain no catalyst, thus preventing abnormal reaction from occurring, and consequently enabling sure prevention of degradation of the fuel electrode and reduction in fuel cell performance. For that purpose, in a fuel cell device, a fuel cell having an electrolyte layer interposed between the fuel electrode and an oxygen electrode includes a cell module laminated so as to interpose a separator formed with the fuel gas flow path along the fuel electrode, and a fuel gas flows substantially perpendicularly to the direction of gravity in the fuel gas flow path. The fuel electrode includes a catalyst-absent portion which contains no catalyst, provided in a portion corresponding to a water-accumulating portion in which water is accumulated, in the fuel gas flow path. | 12-10-2009 |
| 20100081027 | SOLID OXIDE FUEL CELL AND FUEL CELL STACK - A solid oxide fuel cell structured so that an oxidizer gas and a fuel gas are fed to each of multiple power generation cells disposed in parallel relationship through an oxidizer gas passageway and a fuel gas passageway having diverged from each other in a separator. In this structuring, as the gas seal points of the separator can be limited to two points consisting of an oxidizer gas hole and a fuel gas hole, the seal structure of the separator can be simplified. Further, there is provided a solid oxide fuel cell comprising an exhaust gas flow channel disposed in a stack interior so that any exhaust gas resulting from power generation reaction flows in the direction of stacking, wherein the rate of gas flow toward one side along the stacking direction in the exhaust gas flow channel is greater than that toward the other side. In this construction, by virtue of the exhaust gas flowing along the stacking direction in the stack interior, not only is the mid portion of the stack deprived of heat to thereby attain temperature lowering but also the end portions of the stack are heated to thereby attain temperature rise. Accordingly, the temperature distribution along the stacking direction of the stack can be uniformized. | 04-01-2010 |
| 20100092831 | Fuel Cell And Fuel Cell System - The present invention relates to a fuel cell for a fuel cell system, in particular in a motor vehicle, having a plurality of fuel cell elements that form a fuel cell stack, and furthermore having respectively precisely four through openings that align with one another in the fuel cell stack, forming an anode gas inlet canal, an anode gas outlet canal, a cathode gas inlet canal, and a cathode gas outlet canal. In each fuel cell element, the anode gas inlet and the anode gas outlet are diametrically opposite from one another. In each fuel cell element, the cathode gas inlet and the cathode outlet lie diametrically with respect to one another. The fuel cell stack has two end plates on which an anode gas inlet connection, an anode gas outlet connection, a cathode gas inlet connection, and a cathode gas outlet connection are configured, wherein the anode gas inlet connection is configured on the one end plate, while the cathode gas inlet connection is configured on the other end plate. | 04-15-2010 |
| 20100143763 | Laminated Plate Repeating Fuel Cell Unit For an SOFC Stack - An improved SOFC repeating fuel cell unit comprising three flat plates and a cell retainer. The three flat plates are metallurgically joined (brazed or laser welded) into a subassembly to which is added the fuel cell and cell retainer (which may also be joined as a second subassembly). Each flat plate performs a specific set of functions and can be optimized for those functions. Since the plates are flat and designed to overlap in loaded areas, the fuel cell unit is not prone to dimensional collapse which eliminates the internal reinforcements of the prior art design. The cell retainer is formed to provide a self-locating and locking feature for the fuel cell and decouples thermal stresses from the thin ceramic fuel cell. | 06-10-2010 |
