20090029230 | Fuel Cell and Fuel Cell Stack - A fuel cell stack is prepared by laminating multiple fuel cells. Each fuel cell has a first separator, a first resin frame, a second resin frame, and a second separator arranged in this sequence. A membrane electrode assembly or MEA is held between the two resin frames. A layered structure of the two resin frames and seal layers forms an inter-separator inclusion. In the fuel cell, a barcode is provided on an exposed outer surface of the inter-separator inclusion, which has a greater thickness than those of the respective separators. This arrangement enables the barcode to be readily provided and scanned, regardless of the thicknesses and the materials of the respective separators. | 01-29-2009 |
20090068513 | Fuel cell - In a fuel cell, one of separators that are opposed to each other and an intermediate body interposed between the separators are sandwiched by a cell monitor. An end portion of the intermediate body extends to an edge portion of a cell monitor mounting portion of the above-indicated one separator. The intermediate body includes at least one of a member that functions to hold an electrolyte body, a spacer (as in the case where the intermediate body is a resin frame), and a seal member or members. A major surface of the separator in the cell monitor mounting portion on which the cell monitor is mounted is in surface contact with a terminal of the cell monitor for conduction therebetween. | 03-12-2009 |
20090068540 | FUEL CELL, FUEL CELL STACK, AND METHOD OF PRODUCING THE FUEL CELL STACK - A fuel cell has a plurality of constituent members that constitute the fuel cell. The constituent members have first positioning portions and a second positioning portion that is provided on an outer peripheral portion, which are used for positioning during stacking. | 03-12-2009 |
20090104503 | Fuel Cell - A fuel cell has at least one engaging portion that protrudes from an outer edge of a cell and engages with a cell monitor so as to restrict movement of the cell monitor away from the cell. The cell has a plurality of engaging portions that are spaced apart from each other, and the engaging portions engage with one cell monitor at a plurality of positions of the cell. Separators of the cell contact at major surfaces thereof with cell monitor terminals. One cell monitor is mounted on a plurality of cells, and the terminals of the cell monitor are electrically connected to the separators of the cells. | 04-23-2009 |
20100196784 | FUEL CELL, FUEL CELL METAL SEPARATOR, AND FUEL CELL MANUFACTURING METHOD - A fuel cell having a seal structure that exhibits excellent sealing properties and corrosion resistance. By providing a resin layer on at least a portion of an adhesion region where a metal separator contacts an adhesive, a fuel cell having a seal structure that exhibits excellent sealing properties and corrosion resistance can be provided. | 08-05-2010 |

20090017362 | Cell Laminate and Fuel Cell Provided with the Same - There is realized a structure particularly suitable for inhibiting deformation of separators having a structure where the shapes of projections and recesses are inverted from each other on the front side and the back side of each separator as in a pressed metal separator. Between adjacent separators, there is formed either a power generation region where MEAs and frame members for holding at least a part of the MEAs are inserted or a refrigerant flow region where neither the MEAs nor the frame members are inserted. A deformation inhibiting region for inhibiting deformation of each separator is formed by a projection provided on the separator. Also, a projection for inhibiting the separator from deforming at the deformation inhibiting region or nearby is formed on each frame member. The projection is projected toward the back side of the deformation inhibiting region, where the deformation inhibiting region is a recess on the back side of the separator. | 01-15-2009 |
20090269640 | SEPARATOR FOR FUEL CELL - Miniaturization is achieved when a membrane-electrode assembly (MEA) is provided with a cutout, and the flow of a fluid is further smoothened. To realize this, in a separator for a fuel cell according to the present invention, a portion of the contour of a manifold formed in the separator corresponding to a cutout of the membrane-electrode assembly is formed into a shape along the cutout, and a reactant gas or a coolant is supplied or discharged through a portion formed into the shape along the cutout. The cutout is, for example, a corner cut provided in the corner of the membrane-electrode assembly and forming the membrane-electrode assembly into an asymmetric shape. A portion of the contour of the manifold facing this corner cut is preferably formed substantially in parallel with the edge of the corner cut. | 10-29-2009 |
20090286136 | FUEL CELL AND SEPARATOR FOR THE SAME - The contraction and deformation of a seal member are inhibited. To realize this, in a separator in which the shapes of projections and recesses forming at least fluid passages are inverted from each other on the front surface and the back surface of the separator and which is provided with a manifold for supplying and discharging a fluid, the separator, when a seal member for sealing the fluid is provided along the edge side of the separator forming the contour of the manifold, a projecting section capable of functioning as a spacer between the separator and another member adjacent to the separator is provided between the seal member and the edge side. | 11-19-2009 |
20100003580 | FUEL CELL - A fuel cell in which protrusion of an adhesive agent into a gas communication path is suppressed. The fuel cell has a gas passage in a power generation region, a manifold in a non power generation region, and the gas communication path interconnecting the gas passage and the manifold. The adhesive agent is used near at least the gas communication path. An adhesive agent accumulation section for suppressing inflow of the adhesive agent into the gas communication path is located near the gas communication path. | 01-07-2010 |
