20080233439 | METHOD OF ADJUSTING FUEL DISTRIBUTION, MEMBRANE WHICH ADJUSTS FUEL DISTRIBUTION, METHOD OF PRODUCING MEMBRANE WHICH ADJUSTS FUEL DISTRIBUTION, FUEL CELL, AND METHOD OF PRODUCING FUEL CELL - A method of adjusting a fuel distribution includes: adjusting a distribution of a fuel supply amount to a membrane electrode assembly so that a temperature distribution in the membrane electrode assembly becomes substantially uniform by a membrane provided in a fuel supply side of the membrane electrode assembly of a fuel cell. A membrane adjusts a fuel distribution, which is provided in a fuel supply side of a membrane electrode assembly of a fuel cell. The membrane is provided with openings so that a temperature distribution in the membrane electrode assembly becomes substantially uniform. | 09-25-2008 |
20080248357 | Fuel cell seal and fuel cell - A fuel cell seal includes: a first seal member having a first protrusion in a major surface thereof; and a second seal member having a recess in a major surface thereof. The recess is engageable with at least part of the first protrusion. A fuel cell includes: a solid electrolytic film; a first and second seal member placed on both major surface sides of the solid electrolytic film, respectively, and opposed to each other; a fuel electrode placed on a side of the first seal member, the side being opposite to the solid electrolytic film; and an oxidizer electrode placed on a side of the second seal member, the side being opposite to the solid electrolytic film. One of the first and the second seal members has a first protrusion. Other of the first and the second seal members has a recess engageable with at least part of the first protrusion. The first and the second seal members are engaged with each other across the solid electrolytic film. | 10-09-2008 |
20090081486 | FUEL CELL - A fuel cell according to the invention includes: a fuel supply section including a diffusion section configured to diffuse fuel supplied from a fuel supply port in an in-plane direction and an aperture plate having a plurality of apertures configured to emit the fuel from the diffusion section; an oxygen introducing section configured to introduce oxygen from outside; and a power generating section configured to generate electric power by the fuel supplied from the fuel supply section and oxygen supplied from the oxygen introducing section. Aperture ratio of the plurality of apertures provided in the aperture plate has a substantially radial distribution in the in-plane direction such that the aperture ratio is small near the fuel supply port and increases with distance from the fuel supply port. This enables provision of a fuel cell of the spontaneous respiration type where fuel can be uniformly supplied to achieve efficient power generation. | 03-26-2009 |
20090081513 | GAS DIFFUSION LAYER, FUEL CELL, METHOD FOR MANUFACTURING GAS DIFFUSION LAYER, AND METHOD FOR MANUFACTURING FUEL CELL - A gas diffusion layer to be provided on an air electrode of a fuel cell, the gas diffusion layer includes: a portion to be at a relatively high temperature; and a portion to be at a relatively low temperature. Gas permeability of the portion to be at a relatively high temperature is different from gas permeability of the portion to be at a relatively low temperature. | 03-26-2009 |
20090104497 | FUEL ELECTRODE CATALYST, METHOD FOR PRODUCING FUEL ELECTRODE CATALYST, FUEL CELL, AND METHOD FOR PRODUCING FUEL CELL - A fuel electrode catalyst includes: a solid solution of platinum (Pt) and molybdenum (Mo), a crystal structure of the solid solution being a face-centered cubic structure, and a component ratio of the molybdenum (Mo) in the solid solution being from 10 atom % (at %) to 20 atom % (at %), and a method for producing a fuel electrode catalyst, includes: generating platinum hydrate and molybdenum oxide from chloroplatinic acid (H | 04-23-2009 |
