  • Patent number: 7500998
    Abstract: A gas mixture containing a fuel, water and air is supplied to one end of a reforming room, and a reformed gas containing hydrogen is discharged from the other end thereof. Two or more such reforming units are connected in series, and the upstream part of each reforming room is filled with a first catalyst which catalyzes a partial oxidation reaction in an oxygen-rich environment, and the downstream part is filled with a second catalyst which performs the reforming reaction. The gas mixture which has been heated in a heating unit passes through a distribution tube and is distributed evenly to the reforming units. The reforming room is composed of a reforming tube in which a reforming catalyst is charged, or two or more such reforming tubes, parallel to each other. After being reformed the high-temperature reformed gas is passed around the reforming tubes, and fed back to a manifold.

  • Patent number: 7377774
    Abstract: A change-over apparatus for cooling a gas passage is provided with a cooling chamber and a gas cooling and circulating system. The apparatus is further provided with a stationary partition plate and a slidable shield plate. The stationary partition plate has a suction opening and a discharge opening which are independently communicated respectively with a suction port and a discharge port, and the slidable shield plate has a shield part for partially shielding the suction opening and the discharge opening, whereby it is possible to alternately change over the direction of the gas passing through the cooling chamber.

  • Patent number: 7367190
    Abstract: In a supercharger (10) with an electric motor in accordance with the present invention, the electric motor (20) is arranged at a position adjacent to a compressor impeller (6), a center housing (14) has a cooling fluid flow path (34) formed in such a manner as to surround the electric motor (20) and be adjacent to a diffuser portion (25). A first cooling structure portion (38) is formed at a position in the electric motor (20) side in the cooling fluid flow path (34), a second cooling structure portion (39) is formed at a position in the diffuser portion (25) side in the cooling fluid flow path (34). The electric motor (20) is cooled by the first cooling structure portion (38). The diffuser portion (25) is cooled by the second cooling structure portion (39).
