| 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 |

| 20090098433 | Solid oxide fuel cell and separator - A solid oxide fuel cell is formed by arranging a fuel electrode layer and an air electrode layer on both surfaces of a solid electrolyte, respectively, a fuel electrode current collector and an air electrode current collector outside the fuel electrode layer and the air electrode layer, respectively, and separators outside the fuel electrode current collector and the air electrode current collector. In a first embodiment, a fuel gas and an oxidant gas are supplied from the separators to the fuel electrode layer and the oxidant electrode layer, respectively, through the fuel electrode current collector and the air electrode current collector, respectively. Each separator is formed by laminating a plurality of thin metal plates at least including a thin metal plate in which a first gas discharge opening is arranged in a central part and second gas discharge openings are circularly arranged in a peripheral part, and a thin metal plate with an indented surface. Gases discharged from the separators can be supplied to entire areas of the electrode layers through the current collectors, so that electric power generation can be performed. | 04-16-2009 |

| 20080254337 | Solid electrolyte type fuel cell and air electrode current collector used for the same - A solid electrolyte type fuel cell which incorporates a metal separator comprising a base material of a metal other than silver or a silver alloy which is plated with silver or a silver alloy. The fuel cell can achieve improved efficiency for electricity generation with no increase of the resistance of the metal separator, even when it is operated at a low temperature. | 10-16-2008 |
| 20090130522 | Fuel cell module and structure for gas supply to fuel cell - A conductive and tabular separator is inserted into the gap between the fuel electrode layer of an i-th power generating cell and the oxidizer electrode layer of an (i+l)-th power generating cell adjacent to the fuel electrode layer. A fuel supply passage is so formed on one face of each of these separators that a fuel gas flows radially from almost the center of the fuel electrode layer to its edge. An oxidizer supply passage is so formed on the other face that an oxidizer gas outgoes almost uniformly in a shower toward the oxidizer polar layer. Thus, all of the surfaces of the power generating cells contribute to power generation to increase the frequency of collision between the fuel gas and the fuel electrode layer and that between the oxidizer gas and the oxidizer electrode layer, and to improve the generation efficiency. | 05-21-2009 |
