20100189997 | STAINLESS STEEL MEMBER FOR A FUEL CELL - A stainless steel material for a fuel cell, used for a fuel cell or a cartridge for the fuel cell, having a magnetic permeability of 1.000 to 2.500, and forming a layer having a value of chromium atomic %/iron atomic % of not less than 3.0 in the most surface thereof, and/or the layer of thickness of not less than 12 nm calculated as SiO | 07-29-2010 |
20100248079 | COIL SPRING FOR A FUEL CELL - A coil spring for fuel cells, used for a fuel cell or a cartridge for the fuel cell, comprising an austenite type stainless steel without any nickel layer formed on the surface thereof, and having a cationic index I of not more than 60 as expressed by the following formula (1), | 09-30-2010 |
20100266933 | COUPLER FOR FUEL CELL AND FUEL CELL - A coupler for a fuel cell according to the embodiment has a socket and a nozzle. The socket is provided on the fuel cell and has a valve body and an urging component for urging the valve body in the direction of closing it. The nozzle is provided on a fuel cartridge for storing a liquid fuel for the fuel cell and has a valve body and an urging component for urging the valve body in the direction of closing it. The valve bodies are opened to supply the liquid fuel in the fuel cartridge to the fuel cell when the nozzle is connected to the socket. The coupler for a fuel cell has a lubricity providing portion for applying lubricating properties. The lubricity providing portion is disposed on the sliding contact surfaces of the socket and the nozzle and makes sliding contact with each other when the socket and the nozzle are connected to each other or separated from each other. | 10-21-2010 |
20110275004 | FUEL CELL SOCKETS, AND FUEL CELL COUPLERS AND FUEL CELLS USING SAME - A fuel cell socket, to which a fuel cell plug for discharging a liquid fuel for a fuel cell is detachably connected, includes a cylindrical socket body having a diameter-reduced part provided at a substantially intermediate position in an axial direction, a valve having a shaft portion which is protruded toward a connection side through the diameter-reduced part, an elastic cylindrical fuel introduction path which is provided to surround the shaft portion protruded from the diameter-reduced part and has a fastener provided at a side portion, and an auxiliary elastic body which is provided outside the fuel introduction path and pushes the fastener toward the connection side. | 11-10-2011 |
