Patent number: 6129789Abstract: Steam is contacted with a hydrogen absorbing alloy in a temperature range from 200.degree. C. to 400.degree. C. With a contact catalytic reaction of water, a metal contained in the hydrogen absorbing alloy is changed to an oxide or a hydroxide. Hydrogen produced causes the Ni compound to be reduced and thereby the Ni metal that is catalytically active is produced. Thus, the surface of the hydrogen absorbing alloy is activated. The steam is contained in an inert gas or a reductive gas. This treatment method is suitable as an activation treatment for a hydrogen absorbing alloy used as an active material of a negative electrode of a secondary battery.Type: GrantFiled: December 17, 1996Date of Patent: October 10, 2000Assignee: Kabushiki Kaisha Toyoda Jidoshokki SeisakushoInventors: Hiroshi Kawase, Shin-ichi Towata, Kazuhiko Itoh, Shunsuke Yamakawa, Katsushi Abe, Yutaka Ohya, Shinya Morishita

Patent number: 5948563Abstract: An electrode for a sealed nickel/metal hydride battery and a method of manufacturing the same, which is capable of suppressing a decrease in the charging reserve of a hydrogen-storage alloy electrode (negative electrode) and an increase in the internal pressure of the battery, is provided. The hydrogen-storage alloy electrode is formed using a tackifier or a binder which is prepared from an organic polymer material containing the ether linkage (--O--), for example, polyethylene oxide, polypropylene oxide , or polybutylene oxide. The specified material is suitably hydrophilic, and it exhibits an oxidation resistance which is much higher than that of a conventional material containing the hydroxyl group (--OH). Therefore, the specified material is especially resistant to oxidation and decomposition at the positive electrode of the battery and can significantly reduce the production of hydrogen attributed to the oxidation and decomposition.Type: GrantFiled: August 14, 1996Date of Patent: September 7, 1999Assignee: Kabushiki Kaisha Toyoda Jidoshokki SeisakushoInventors: Hiroshi Kawase, Shinya Morishita, Shinichi Towata, Kenichi Suzuki, Katsushi Abe

Patent number: 5401371Abstract: A hydrogen generator includes a water tank adapted to form a water chamber, and a water electrolysis cell disposed in the water tank. The water electrolysis cell includes a proton conductive membrane, an oxygen generator chamber side separator adapted to form an oxygen generator chamber, and a hydrogen generator chamber side separator adapted to form a hydrogen generator chamber, and a hydrogen outlet passage adapted to discharge generated hydrogen out of the hydrogen generator chamber.

Patent number: 5272871Abstract: Hydrogen gas from a hydrogen generator which creates hydrogen gas by the electrolysis of water or water vapor is supplied at the entrance to a catalyzer provided in an exhaust line. The catalyzer performs a catalytic reaction between hydrogen gas and nitrogen oxides to achieve decomposition into nitrogen gas and water vapor in the exhaust from an internal combustion engine. The nitrogen oxides are directly reduced with said hydrogen gas in a low temperature atmosphere not higher than 350.degree. C. to achieve efficient reduction in the nitrogen oxides. The improved method and apparatus provide a catalytic system with which the nitrogen oxides in the exhaust from a lean burnt engine or a diesel engine can be effectively reduced irrespective of the concentration of oxygen gas in the exhaust without impairing the good fuel economy of those engines.Type: GrantFiled: May 22, 1992Date of Patent: December 28, 1993Assignee: Kabushiki Kaisha Toyota Chuo KenkyushoInventors: Yujiro Oshima, Katsushi Abe, Kazuo Kawahara, Koji Yokota, Hideaki Muraki, Masayuki Fukui
