20160126563 | INSULATOR AND FUEL CELL DEVICE - In order to prevent a reduction in workability when inserting an insulator, the insulator is to be disposed between a stacked body having a cell stack including a plurality of stacked unit cells and an end member to be disposed outward from the cell stack in stacking directions of the plurality of unit cells, and a covering to be disposed so as to separate in a perpendicular direction to the stacking directions from a side face of the stacked body parallel to the stacking directions. In a state where an end portion of the end member in the perpendicular direction is closer to the covering than an end portion of the cell stack in the perpendicular direction, and the insulator is disposed between the stacked body and the covering, the insulator includes a planar portion for covering at least a part of the side face, and a protruded portion disposed in the planar portion and protruded toward one or more unit cells near the end member among the plurality of unit cells constituting the cell stack. | 05-05-2016 |
20160133951 | Insulator and Fuel Cell - In order to improve a power density of a fuel cell and prevent a generation of a poor insulation, an insulator is provided, which is disposed between a current collector disposed in contact with one end of a stacked body having a plurality of stacked unit cells in stacking directions, and an end member disposed outside from the current collector in the stacking directions, and includes a plurality of insulator members, each having a sheet-like planar portion. The plurality of insulator members which are stacked onto each other by the planar portions thereof are disposed oppose to the current collector. | 05-12-2016 |
20160133952 | Fuel Cell End Plate, Method of Manufacturing Same, and Fuel Cell - A fuel cell end plate that is provided at an end portion of a fuel cell includes a through-hole which penetrates the end plate and through which at least one of a fuel gas, an oxygen containing gas and cooling water fed to the fuel cell is distributed and a seal which covers an inner circumferential surface of the through-hole and a circumferential edge surface around the through-hole. The cutting processing mark of a corner portion connected from the inner circumferential surface of the through-hole to the circumferential edge surface is a processing mark in which a curved surface processing mark that is formed with a curved surface from any one of the inner circumferential surface and the circumferential edge surface toward the side of the other surface and a linear processing mark that is formed from the curved surface processing mark to the other surface and that is a straight line in a cross section in an axial direction of the through-hole are continuous. | 05-12-2016 |

20160133984 | FUEL CELL AND FUEL CELL SYSTEM - A fuel cell includes a stacked body formed by stacking a plurality of unit cells, an end plate arranged on at least one end of the stacked body in a stacking direction, a fuel cell case including an opening portion and incorporating the stacked body, wherein the opening portion has a substantially polygonal outer circumference shape with a plurality of corners, and a plurality of types of fasteners with different load resistances that fix the end plate, closing the opening portion of the fuel cell case, to the fuel cell case. A fastener, of the plurality of types of fasteners, of a type with a highest load resistance is arranged at at least one of the plurality of corners of the opening portion. | 05-12-2016 |
20160141640 | FUEL CELL SYSTEM - A fuel cell system mounted on a vehicle, includes: a fuel cell configured to cause electrochemical reaction between an anode gas and a cathode gas to proceed; and a fuel cell casing that is configured to place the fuel cell therein, wherein the fuel cell casing has a bottom face that is formed in an approximately rectangular shape, the fuel cell casing is positioned such that longitudinal sides of the approximately rectangular shape are parallel to a left-right direction of the vehicle, and the bottom face has a rib that is extended only in a front-back direction of the vehicle is provided on the bottom face. | 05-19-2016 |
20160141658 | Gas-Liquid Separator and Fuel Cell System - A gas-liquid separator includes a gas-liquid separator forming portion that is provided in an end plate, and a cover member. The gas-liquid separator forming portion includes a first inner wall portion that serves as a flow path for an off-gas and forms a part of an accumulating portion, the first inner wall portion having a shape recessed in a thickness direction of the end plate. The cover member includes a second inner wall portion that has a shape recessed in a thickness direction of the cover member, the second inner wall portion being disposed to face the first inner wall portion in a stack direction and forming the accumulating portion together with the first inner wall portion. | 05-19-2016 |
20160141693 | GAS LIQUID SEPARATOR AND FUEL CELL SYSTEM - The gas liquid separator comprises a gas liquid separator-forming portion formed in an end plate of a fuel cell to have an opening at an end face of the end plate and that constitutes part of the gas liquid separator; and a cover member located to cover the opening and is combined with the gas liquid separator-forming portion to constitute the gas liquid separator. The gas liquid separator-forming portion includes a first inner wall portion provided to serve as a flow path of the off-gas and form part of a reservoir and that is configured to include an off-gas outlet, to be connected with the opening and to be formed concave in a thickness direction of the end plate; and a surrounding portion protruded from the first inner wall portion along a first direction from the gas liquid separator-forming portion toward the cover member to surround the off-gas outlet. | 05-19-2016 |
20160141701 | FUEL CELL DEVICE - A fuel cell device includes a fuel cell body, a case and a pin having one end contacting a part of the fuel cell body. A through hole is formed in the case. The through hole penetrates the case from the outside to the inside. The pin is inserted in the through hole and provided with a sealing member formed on at least a part of an outer circumferential surface. The through hole has a constant inner diameter from a position inside the case to a border with the outside.
