Patent number: 7311760Abstract: Provided is an inexpensive temperature-humidity exchanger having reliably gas-sealed gas manifolds and delivering a gas at high pressure and high dew-point temperature. Upper and lower seal portions surrounding gas manifolds to which the gas is supplied or from which the gas is discharged are provided. The upper and lower seal portions, which partially extend across an aggregate communication groove, are respectively constituted by upper and lower seal formation plates that are arranged in a two-stage manner in a laminating direction. The upper and lower seal portions have flat faces extending in the laminating direction. Furthermore, the upper and lower seal formation plates are disposed such that their projections in the laminating direction are offset from each other.Type: GrantFiled: February 4, 2005Date of Patent: December 25, 2007Assignee: Mitsubishi Denki Kabushiki KaishaInventors: Mitsuie Matsumura, Yoshihide Gonjo, Hideo Ichimura

Patent number: 6159434Abstract: A fuel reforming apparatus comprising a liquid feed heating portion, an evaporation portion, a steam superheating portion, a reforming portion, a shift reaction portion, a CO oxidization portion, a catalytic combustion portion, and a heat recovery portion. These portions are constituted by flat plates provided with heat-transfer fins in the interior and are stacked into an integral structure, thereby obtaining a temperature distribution along a stacked direction so that the flat plate elements reach a temperature suitable for reforming, combustion, evaporation, shift, and CO oxidization.Type: GrantFiled: February 10, 1998Date of Patent: December 12, 2000Assignee: Engineering Advancement Association of Japan Mitsubishi Denki Kabushiki KaishaInventors: Yoshihide Gonjo, Teruo Sugimoto, Minoru Satoh

Patent number: 4774152Abstract: A reforming catalyst adapted for use with fuel cells is disclosed which is free from degradation in catalytic activity even if subjected to a fuel gas containing an electrolyte or substances resulting therefrom, and which has stable and high catalytic activity for an extended period of time. The reforming catalyst includes a catalytically active substance adapted to reform a fuel gas containing hydrocarbons or alcohols into a fuel gas containing hydrogen and carbon monoxide, and an electrolyte-removing substance adapted to remove an electrolyte and/or substances resulting therefrom in the fuel cell. The electrolyte-removing substance has a porous structure and comprises a compound containing at least one of silicon, aluminum and chromium which chemically reacts with the electrolyte and/or the substances resulting therefrom for removal thereof.Type: GrantFiled: April 6, 1987Date of Patent: September 27, 1988Assignee: Mitsubishi Denki Kabushiki KaishaInventors: Mitsuie Matsumura, Tatsunori Okada, Yoshihide Gonjo
