Patent number: 7115159Abstract: In a hydrogen storing tank (solid filling tank) in which a hydrogen absorbing alloy (solid) is filled, a heat exchanger for executing heat exchange with the hydrogen absorbing alloy is constructed by laminating alternately first heat-transferring fins formed in corrugated plate shape and second heat-transferring fins formed in flat plate shape. Partitioned portions that are partitioned by the first heat-transferring fins and the second heat-transferring fins restrict movement of hydrogen absorbing alloy powders (MH powders) in a subsiding direction. Therefore, movement of the MH powders can surely be prevented by not using members that has no concern with the heat exchange and reduces an amount of filled MH powders and a volume in which the heat exchanger is provided.Type: GrantFiled: November 14, 2003Date of Patent: October 3, 2006Assignee: Kabushiki Kaisha Toyota JidoshokkiInventors: Katsuyoshi Fujita, Hidehito Kubo, Keiji Toh, Akiko Kumano, Daigoro Mori

Patent number: 7029521Abstract: Process in conjunction with the production of oxygen (22), wherein incoming air (10, 16, 16a, 16b,) is brought to pass through a sorbent/zeolite structure (18), which comprises at least three zeolite units (50a–f) intermittently operated in a first stage comprising adsorption of nitrogen from the air and a second stage comprising desorption (20, 20a, 20b) of thus adsorbed nitrogen. At least two of the zeolite units are operated in the adsorption stage, the incoming air being brought to pass consecutively (53a) through the at least two zeolite units to form an increasing nitrogen gradient; and/or at least two units of the zeolite units are operated in the desorption stage, a pressure being released and/or a desorbing gas (22a, 22b) being brought to pass consecutively (53b) through the at least two zeolite units to form a decreasing nitrogen gradient in the zeolite units.Type: GrantFiled: September 23, 2002Date of Patent: April 18, 2006Assignee: Ifo Ceramics AktiebolagInventor: Thomas Johansson

Patent number: 7025931Abstract: The present invention reduces the amount of oxygen in an oxygen-containing gas within a closed environment. A selected amount of hydrogen gas is mixed with a portion of the oxygen-containing gas from the closed environment to form a first gas mixture. A catalyst exposed to the first gas mixture causes a reaction between the hydrogen and at least a portion of the oxygen therein. The resulting second gas mixture, which is returned to the closed environment, has a lower percentage of oxygen. At least one oxygen sensor is positioned in the closed environment to determine when oxygen levels in the closed environment reach a threshold level. The output signal from the sensor is used to control when and/or how much hydrogen is mixed in the first gas mixture.Type: GrantFiled: December 31, 2001Date of Patent: April 11, 2006Assignee: The United States of America as represented by the Secretary of the NavyInventors: Marshall L. Nuckols, Kirk Vanzandt

Patent number: 6991770Abstract: A hydrogen storage tank has an outer cylinder and a cylindrical hydrogen storage module within the outer cylinder spaced apart from an inner peripheral surface of the outer cylinder to provide a hydrogen passage therebetween. The cylindrical hydrogen storage module includes a lamination having a plurality of hydrogen storage units filled with powdery hydrogen absorption material and a hydrogen absorption and desorption surface on an entire outer peripheral surface, while interposing a heating/cooling element between ones of adjacent units. First and second main passages penetrate the lamination in a lamination direction of the units, and permit heating fluid and cooling fluid to flow therethrough. Sub passages branch from the main passages and extend over within each of the heating/cooling elements.Type: GrantFiled: April 11, 2001Date of Patent: January 31, 2006Assignee: Honda Giken Kogyo Kabushiki KaishaInventors: Takanori Suzuki, Izuru Kanoya, Mitsuya Hosoe

Patent number: 6984258Abstract: Method and apparatus for treating a gas by adsorption. A gas is compressed and then treated by being circulated in an adsorber. A regenerating fluid is indirectly heated by the gas coming from the compressor. In a second regeneration phase, the regenerating fluid is sent directly to the adsorber, while the treated gas is refrigerated by an auxiliary refrigerator.Type: GrantFiled: October 9, 2002Date of Patent: January 10, 2006Assignee: L'Air Liquide, Société Anonyme à Directoire et Conseil de Surveillance pour l'Etude et l'Exploitation des Procédés Georges ClaudeInventors: Norbert Niclout, Marc Wagner
