20100062315 | METHANOL FUEL CELL CARTRIDGE - The present invention provides a cartridge for a methanol fuel cell at low cost, which does not show deterioration in electric power generation performance, can be operated for a prolonged period of time, and can be reduced in size and weight. In the present invention, the cartridge for a methanol fuel cell has an inner resin layer containing a resin having such a property that, after a film of the resin is immersed in methanol at 60° C. for 7 days, the methanol is diluted twice in terms of a volume ratio with distilled water at room temperature to give a liquid, the liquid shows a light transmittance of 10% or higher at 300 nm. | 03-11-2010 |
20100136458 | FUEL FOR FUEL CELL, FUEL CARTRIDGE FOR FUEL CELL AND FUEL CELL - Disclosed is a fuel for fuel cells which contains at least one organic compound selected from the group consisting of methanol, ethanol, dimethyl ether and formic acid, and 1-200 ppm of a hydrocarbon compound in terms of a single component as determined by gas chromatography mass spectrometry. Also disclosed are a fuel cartridge for fuel cells and a fuel cell. | 06-03-2010 |
20100167172 | ELASTIC MEMBER FOR METHANOL FUEL CELL CARTRIDGE - This invention provides an elastic member for a methanol fuel cell cartridge, comprising an elastomer having a compression set of 1 to 80 and a hardness (type A) of 40 to 70 and having an operating limit time of 10,000 hours or more determined by a DMFC performance test for the fuel cell. The elastic member can prevent leakage of methanol from a methanol fuel cell cartridge, or a connection part between the cartridge and a fuel cell body and, at the same time, can realize long-term operation of the fuel cell without causing deterioration of power generation performance. | 07-01-2010 |
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 |
20130183607 | METHANOL FUEL CELL CARTRIDGE - The present invention provides a cartridge for a methanol fuel cell at low cost, which does not show deterioration in electric power generation performance, can be operated for a long period of time, and can be reduced in size and weight. In the present invention, the cartridge for a methanol fuel cell has art inner resin layer containing a resin having such a property that, after a film of the resin is immersed in methanol at 60° C. for 7 days, the methanol is diluted twice in terms of a volume ratio with distilled water at room temperature to give a liquid, the liquid shows a light transmittance of 10% or higher at 300 nm. | 07-18-2013 |

20090197150 | FUEL CELL CARTRIDGE - A fuel cell cartridge for containing fuel for fuel cells, comprising a polyester resin, wherein after the fuel is contained and preserved at 60° C. for one week, a change of density at the bottom portion and the mouth portion is 0.01 g/cm | 08-06-2009 |
20100181315 | OXYGEN BARRIER CAP WITH PULLRING - The present invention is to provide an oxygen barrier cap with pull ring that maintains the opening easiness by tearing off with a pull ring, and the high productivity of one-piece molding by injection molding, and enhances significantly the gas barrier property, particularly oxygen barrier property. Further, in order to prevent conventional contamination of stored content caused by metal dust generated by tearing off the metal foil, or use of gas barrier resin molding material, the oxygen barrier cap with pull ring is molded from thermoplastic resin, and fixed to an opening of a container, and an oxygen barrier agent is coated on a score surface of a cap with pull ring, to form a coating film with oxygen barrier property. | 07-22-2010 |
20110139300 | REFUELLING CONTAINER FOR FUELCELL, METHOD FOR REFUELLING, AND HOLDER FOR REFUELLING CONTAINER - In, for example, a direct methanol type fuelcell, fuel is allowed to be injected little by little when the fuel is injected and supplied from the outside to a fuel receiving part reduced in the amount of remaining fuel on the fuelcell body side and an electromotive part can be prevented from being damaged by keeping the pressure in the fuel receiving part at a fixed level or less when the fuel is injected. Specifically, when a fuel CL filled in a refuelling container C is injected into a fuel receiving part T in several lots, a fuel injecting operation is repeated in which the volume of the refuelling container C is shrunk and reduced to supply the fuel into the fuel receiving part T in a proper amount and then the original volume of the refuelling container is restored to thereby absorb the atmospheric gas in the fuel receiving part T, which makes it possible to inject fuel continuously without any hindrance to the injection of the fuel. | 06-16-2011 |
