Patent number: 6783877Abstract: In a fuel cell system 10, a cracking unit 20 is provided upstream of a reformer 36. When the cracking unit 20 is supplied with oxygen and gasoline as a hydrocarbon-based fuel, the gasoline is partially oxidized and decomposed using oxidation-generated heat to give a hydrocarbon with a lower carbon number. The hydrocarbon with the lower carbon number obtained by such gasoline pyrolysis is fed to the reformer 36 and supplied to a reforming reaction zone.Type: GrantFiled: August 17, 2001Date of Patent: August 31, 2004Assignee: Toyota Jidosha Kabushiki KaishaInventors: Takashi Shimazu, Satoshi Iguchi, Satoshi Aoyama, Koichi Numata, Kazuhisa Kunitake, Takeshi Nishikawa, Shuichi Kubo, Satoshi Yamazaki

Patent number: 6776809Abstract: A heat exchanger 32 comprises a first heat exchanger 40 for allowing heat to be exchanged between water and a reformed gas from a reforming reactor, a second heat exchanger 50 for spraying and vaporizing water in the reformed gas from the first heat exchanger 40, and a third heat exchanger 60 for vaporizing unvaporized or precipitated water. The reformed gas from the reforming reactor is cooled by the heating and vaporizing of water, and is mixed with the vaporized water and fed as mixed gas to a water gas shift reactor. The processes of cooling the reformed gas, heating and vaporizing of the water, and mixing the reformed gas and steam are completed in the heat exchanger 32, making it possible to design a smaller, simpler, and more efficient apparatus.Type: GrantFiled: May 21, 2001Date of Patent: August 17, 2004Assignee: Toyota Jidosha Kabushiki KaishaInventor: Takashi Shimazu

Patent number: 6743537Abstract: In a system for generating hydrogen gas by reforming raw material, steam is continuously supplied while the supply of raw material and air to a reforming unit is stopped, so as to purge residual flammable material within the system with steam such that even if oxygen is supplied, heat generated by a reaction between the residual flammable material within the system and the oxygen does not effect the system, and the steam is removed from the system by air purging so as to prevent adverse effects from condensation.Type: GrantFiled: December 7, 2001Date of Patent: June 1, 2004Assignee: Toyota Jidosha Kabushiki KaishaInventor: Takashi Shimazu

Patent number: 6338472Abstract: Mists atomized from siphon type two-fluid nozzles 14a and 14b are made to collide with each other within a secondary gas intake conduit 16 and secondary gas is supplied toward a collision point of the mists. A flow control plate 22 is provided within the secondary gas intake conduit 16 at a point upstream from the collision point to ensure that the secondary gas does not interfere with the collision of the mists and also to promote fine mists generated by the collision of the mists to mix with the secondary gas. Further, a secondary nozzle 24 is provided at the tip of the secondary gas intake conduit 16 to jet the secondary gas including the fine mists from the secondary nozzle 24. In the case of applying this mist atomizer 10 to the fuel cell 30, droplets and liquid water in the process gas is separated and removed at the mounting portion of the mist atomizer 10 in order to selectively supply mist of equal-sized particles only into the fuel cell.Type: GrantFiled: May 17, 2000Date of Patent: January 15, 2002Assignee: Kabushiki Kaisha Toyota Chuo KenkyushoInventors: Takashi Shimazu, Hiroshi Aoki
