20080241615 | HYDROGEN SUPPLY DEVICE, DISTRIBUTED POWER SUPPLY SYSTEM USING SAME, AND AUTOMOBILE USING SAME - There is provided a hydrogen storage and/or supply device utilizing an organic compound medium capable of being repeatedly hydrogenated and dehydrogenated. This device comprises: a catalyst member formed of a stack of a plurality of catalyst plates for storing and/or releasing hydrogen through a chemical reaction of the organic compound medium by means of a metal catalyst; a heat collector plate for supplying heat from a heat source to the catalyst member; and a heat transfer portion in contact with the plurality of catalyst plates and the heat collector plate. Each catalyst plate includes: the metal catalyst; a substrate; a catalyst support formed on at least one face of the substrate for supporting the metal catalyst; and a flow channel for passing the organic compound medium therethrough. Furthermore, the heat transfer portion has a thermal conductivity higher than that of the catalyst support. | 10-02-2008 |
20090000574 | Organic Hydride Reactor and Hydrogen Generator - An organic hydride reactor generates hydrogen by electrolyzing electrolyte to manufacture the organic hydride from the generated hydrogen. The system has a anode and cathode opposed to each other, the electrolyte supplied between the anode and cathode, a hydrogenation catalyst performing hydrogenation reaction between the hydrogen supplied from the anode by electrolysis and organic compound. The anode cathode has gas-fluid separation function and the electrolyte is supplied to only one surface of the anode and cathode, and a gas caused by electrolysis is discharged from a surface not being in contact with the electrolyte of the anode and cathode. | 01-01-2009 |
20090000575 | Engine System - An object of the present invention is, in an engine system including a medium which chemically repeats storage and release of hydrogen, to provide an engine system where CO | 01-01-2009 |
20090152118 | Electrolyzer and electrodes - An the electrode for electrolysis of an electrolytic solution comprises an electrode core serving as a base and a plurality of prominences formed on a surface of the electrode core, the prominences have each a leaf-shaped form and rises from the electrode core surface. | 06-18-2009 |
20090246088 | DEHYDROGENATION FUEL THEFT PREVENTION SYSTEM - A dehydrogenation fuel theft prevention system for preventing the theft of dehydrogenation organic fuel containing hydrogen is provided. The dehydrogenation fuel theft prevention system is for systems including a reformer for dehydrogenating organic fuel containing at least hydrogen and a dehydrogenation fuel recovery tank for storing dehydrogenation fuel produced when organic fuel is dehydrogenated in the reformer. The theft prevention system is provided with a means for mixing an odorant as a component with a pungent odor other than the fuel components or a agent for coagulating the fuel components. The odorant or the coagulating agent is mixed when fuel is manufactured, distributed, utilized, recovered, or stored or fuel is about to be stolen. | 10-01-2009 |
20130168237 | HYDROGEN PRODUCTION SYSTEM - Hydrogen production apparatus including an electrode pair including hydrogen electrode and oxygen electrode, a partition wall interposed between the hydrogen electrode and the oxygen electrode, and a tank containing the electrode pair, the partition wall, and an aqueous electrolyte solution, the hydrogen production apparatus generating hydrogen by electrolysis of the aqueous electrolyte solution by the electrode pair, in which the oxygen electrode includes an oxide or a hydroxide of a metal, and the specific surface area of the oxygen electrode is larger than that of the hydrogen electrode. Deterioration of the electrode caused by oxidation-reduction can be suppressed and the response to the fluctuation of an inputted power by the renewable energy, and reliability can be improved since a potential at the oxygen electrode can be kept at a predetermined level or higher in the hydrogen production apparatus. | 07-04-2013 |
20140079593 | RENEWABLE ENERGY STORAGE SYSTEM - A renewable energy storage system that stores renewable energy, includes: an electrical power generator that converts renewable energy into electrical power; an electrical storage device that stores the electrical power; a hydrogen production device that produces hydrogen using the electrical power from the electrical power generator and/or the electrical power stored in the electrical storage device; a hydrogenation device that adds the hydrogen produced by the hydrogen production device to the unsaturated hydrocarbon; a saturated hydrocarbon storage device that stores the saturated hydrocarbon produced by the addition of the hydrogen to the unsaturated hydrocarbon; an unsaturated hydrocarbon storage device that stores the unsaturated hydrocarbon; and an unsaturated hydrocarbon supply controller that controls the supply of unsaturated hydrocarbon stored in the unsaturated hydrocarbon storage device to the hydrogenation device. | 03-20-2014 |
