  • Hydrogen production method, hydrogen production system, and fuel cell system
    Patent number: 8460834
    Abstract: A hydrogen production method includes: a first process in which nitrogen compounds of metal and water are reacted to produce ammonia and hydroxide of the metal; a second process in which hydrogen compounds of a metal and the ammonia produced in the first process are reacted; and a third process in which hydrogen compounds of a metal and the hydroxide of the metal produced in the first process are reacted.
    Type: Grant
    Filed: September 26, 2008
    Date of Patent: June 11, 2013
    Assignees: Toyota Jidosha Kabushiki Kaisha, Hiroshima University
    Inventors: Kyoichi Tange, Yoshitsugu Kojima, Takayuki Ichikawa, Chie Oomatsu, Satoshi Hino, Hironobu Fujii
  • Activation method for lithium hydride, and hydrogen generation method
    Patent number: 8026001
    Abstract: A lithium hydride activation method includes: a nitrification treatment process of reacting lithium hydride with a nitride and therefore forming a chemical compound layer stable to the nitride, on a surface of the lithium hydride; and a particle size reduction process of reducing a particle size of the lithium hydride provided with the chemical compound layer by a mechanical pulverization treatment after the nitrification treatment process is performed. A hydrogen generation method includes generating hydrogen by reacting ammonia with the lithium hydride activated by the activation method.
