20090269647 | CARTRIDGE FOR METHANOL FUEL CELL - Disclosed is a small-sized, light-weighted, low-cost cartridge for methanol fuel cells which has excellent permeation-preventing performance (barrier properties) against methanol and oxygen. This cartridge is suitably used as a fuel tank or refill container for a direct methanol fuel cell (DMFC). Specifically disclosed is a cartridge for methanol fuel cells comprising at least one methanol impermeable layer having a methanol vapor permeability coefficient of not more than 15 μg·mm/m | 10-29-2009 |
20100015498 | METHANOL FUEL CELL CARTRIDGE - Provided is a methanol fuel cell cartridge formed of a container comprising a polyester-based resin layer which has a methanol vapor permeability coefficient at 40° C. of 3 μg·mm/m | 01-21-2010 |
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 |
