  • Publication number: 20040062964
    Abstract: A fuel cell system having one or more anodes, one or more cathodes and electrolytes put therebetween is provided with a fuel supply unit, an air supply unit and a heat exchanger. The fuel supply unit supplies fuel to the anodes. The air supply unit supplies air to the cathodes. The heat exchanger is provided with a drain connected to the fuel supply unit and exchanges heat between the air supplied to the cathodes and exhaust gas exhausted from the anode so as to condense water from the exhaust gas and discharge the water to the drain.

  • Publication number: 20040052677
    Abstract: The present invention relates to a Ni base alloy having sufficient strength at high temperatures and high corrosion resistance at high temperatures in a high-temperature composite corrosive environment in which chlorination or sulfidation occurs simultaneously with high-temperature oxidation, without excessive cooling or surface protection. According to the present invention, a Ni base alloy having high-temperature strength and corrosion resistance includes Cr in a range of from 25 to 40 weight %, Al in a range of from 1.5 to 2.5 weight %, C in a range of from 0.1 to 0.5 weight %, W of 15 weight % or less, Mn of 2.0 weight % or less, Si in a range of from 0.3 to 6 weight %, Fe of 5 % or less, and Ni of rest except inevitable impurities. When strength at high temperatures is allowed to be small, W is in a range of from 0 to 8 %, and Si is in a range of from 0.3 to 1 % or from 1 to 6 %. In order to enhance strength at high temperatures, W is in a range of from 8 to 15, and Si is in a range of from 0.

  • Publication number: 20040045272
    Abstract: The present invention relates to a method and apparatus for effectively utilizing thermal energy possessed by a high-temperature combustion gas discharged from a combustor and utilizing high-temperature oxygen contained in the high-temperature combustion gas discharged from the combustor. A fluidized-bed gasification apparatus for gasifying combustibles in a fluidized-bed furnace comprises a gasification furnace (2) for gasifying combustibles therein, and a combustion furnace (1) for combusting combustible components therein. The fluidized medium moves between the gasification furnace (2) and the combustion furnace (1), and exhaust gas discharged from another combustor is utilized as a fluidizing gas in the combustion furnace (1).

  • Patent number: 6579642
    Abstract: A battery device designed so that a plurality of battery modules (1) are arranged in rows at given spaces in a enclosure (2). Turbulence accelerators (5), such as dummy battery units or the like, are provided in a position on the uppermost-stream side of the enclosure in which air flows in the direction of arrangement of the battery modules. The heat transfer ability for the battery modules in the upper-stream position is enhanced by the turbulence accelerators which disorders the airflow introduced into the enclosure. Auxiliary coolant intake ports (7) for the introduction of a coolant are provided in the middle of an airflow path, whereby the heat transfer ability on the lower-stream side is enhanced, so that battery temperature differences between the battery units arranged in the enclosure can be restrained. Thus, a simple-construction battery device is realized enjoying improved quality and operation stability.
