20080261104 | FUEL CELL - Auxiliary seals are provided on a surface of a first metal separator, between load receivers and an oxygen-containing gas supply passage, a fuel gas supply passage, an oxygen-containing gas discharge passage, and a fuel gas discharge passage, in relatively wide areas. The cross sectional shape of the auxiliary seal is the same as those of a flow field seal and ring-like seals, and the auxiliary seals are formed independently from the flow field seal and the ring-like seals. | 10-23-2008 |
20090081509 | FUEL CELL - A first seal member is provided integrally on a surface of a first metal separator. The first seal member includes a base portion provided integrally on the first metal separator, a columnar portion protruding from the base portion, and a curved edge portion provided on the columnar portion. The curved edge portion has a predetermined radius of curvature. | 03-26-2009 |
20090291350 | ELECTROLYTE ELECTRODE ASSEMBLY AND FUEL CELL - A unit cell of a fuel cell is formed by sandwiching a membrane electrode assembly between a first metal separator and a second metal separator. The membrane electrode assembly includes a solid polymer electrolyte membrane having a reinforcement member on both surfaces of the outer end of the solid polymer electrolyte membrane. Frame members are provided on the reinforcement member outside an anode, and a fuel gas inlet channel and a fuel gas outlet channel are formed by the frame members, at positions corresponding to a fuel gas inlet buffer and a fuel gas outlet buffer. | 11-26-2009 |
20100003564 | FUEL CELL - Flow guides forming an inlet channel are formed on a surface of a metal separator of a fuel cell. The flow guides overlap a section of an outer seal provided on the other surface of the metal separator. When a load is applied to the flow guides and the overlapping section in a stacking direction of the fuel cell, the flow guides and the overlapping section are deformed substantially equally in the stacking direction to the same extent. The line pressure of the flow guides and the line pressure of the overlapping section are substantially the same. The seal length L | 01-07-2010 |
20110269049 | FUEL CELL - Flow guides forming an inlet channel are formed on a surface of a metal separator of a fuel cell. The flow guides overlap a section of an outer seal provided on the other surface of the metal separator. When a load is applied to the flow guides and the overlapping section in a stacking direction of the fuel cell, the flow guides and the overlapping section are deformed substantially equally in the stacking direction to the same extent. The line pressure of the flow guides and the line pressure of the overlapping section are substantially the same. The seal length L | 11-03-2011 |
20120021326 | FUEL CELL STACK HAVING TIGHTENING MEMBERS - A fuel cell stack includes a stack body formed by stacking a plurality of fuel cells in a stacking direction, and first and second end plates at both ends in the stacking direction. Long sides of the first and second end plates are fixed together by a pair of tightening members. The tightening member includes a bent portion bent in a direction along a surface of the second end plate, and coupled to the pressure application adjustment device, and a wide portion having a width extended toward the first end plate. | 01-26-2012 |
20120183881 | FUEL CELL WITH PROTRUDED GAS DIFFUSION LAYER - An assembling operation of a fuel cell is effectively simplified. With the simple and economical structure, the desired sealing function is achieved. The fuel cell ( | 07-19-2012 |
20120321980 | FUEL CELL - A fuel cell unit configuring a fuel cell is provided with a first separator, a first electrolyte film/electrode body, a second separator, a second electrolyte film/electrode body, and a third separator. Resin guide members are provided on the outer periphery of the first separator, the second separator, and the third separator. The resin guide members have outer peripheral ends which protrude outwards, and in the aforementioned resin guide members are formed concave reliefs which are spaced inwards from the aforementioned outer peripheral ends. | 12-20-2012 |
20130337358 | FUEL CELL - A fuel cell stack comprising a second metal separator set to have an external dimension larger than a first metal separator, wherein the second metal separator comprises, formed integrally, a first seal member in contact with the peripheral edge of a first electrolyte membrane/electrode structure, a second seal member in contact with the peripheral edge of the first metal separator, and a third seal member in contact with the peripheral edge of an adjoining fourth metal separator. Since the first seal member, the second seal member and the third seal member are integrally formed on one surface of the second separator or one surface of the first separator, a seal-forming step can be carried out at one effort, simply and economically. In addition, use of a triple seal structure containing the first through the third seal members can favorably improve the sealing feature of reaction gas and minimize reaction gas leakage. | 12-19-2013 |
20140322627 | FUEL CELL - A power generation unit of a fuel cell includes a first metal separator, a first membrane electrode assembly, a second metal separator, a second membrane electrode assembly, and a third metal separator. The first metal separator includes first ridges for positioning the first membrane electrode assembly. The second metal separator includes second ridges for limiting movement of the first membrane electrode assembly. | 10-30-2014 |
20150041299 | OPERATING DEVICE FOR VEHICLE - This operating device for a vehicle includes: a holding portion provided at a steering wheel of the vehicle and adapted to be held by an operator; a first operation member provided on a surface of the holding portion, the first operation member having a first operating surface that is operatable by a finger of the operator through a contact operation and through a tilting operation; and a second operation member provided at a central portion of the first operating surface, the second operation member having a second operating surface that is operatable by the finger of the operator through a contact operation and through a pressing operation, wherein the first operating surface has an annular concave shape with the central portion being furthest recessed to an inside. | 02-12-2015 |
