  • Particulate matter amount detection system
    Patent number: 9354154
    Abstract: A porous structure including a pair of electrodes disposed in a flow direction of exhaust gas and a solid electrolyte interposed between the electrodes is arranged in an exhaust passage of an internal combustion engine, and the amount of a particulate matter in exhaust gas is specified based on a potential difference generated between the electrodes.
    Type: Grant
    Filed: June 7, 2011
    Date of Patent: May 31, 2016
    Assignees: TOYOTA JIDOSHA KABUSHIKI KAISHA, THE RITSUMEIKAN TRUST
    Inventors: Hiroki Nishijima, Shinji Ikeda, Keiichiro Aoki, Yoshinobu Yoshihara, Yasufumi Nakanishi, Takaya Suzuki
  • Fuel cell, fuel cell apparatus, vehicle and co-generation system including the same and fuel cell operation method
    Patent number: 8367263
    Abstract: A fuel cell apparatus is capable of quickly heating a solid electrolyte to a proper temperature in order to perform effective electric power generation. The apparatus includes a fuel cell (1) for generating electric power by cell reacting a fuel gas on an anode-(3) side with oxygen on a cathode-(4) side. The fuel cell (1) includes a solid electrolyte (2) formed of a porous mass and uses a differential pressure to cause the fuel gas on the anode-(3) side to permeate through the solid electrolyte to the cathode-(4) side. The solid electrolyte (2) is heated by combustion reaction of the fuel gas permeated through the solid electrolyte (2) and mixed with the oxygen.
