| 20080280171 | Hydrogen Generation Device, Operation Method Thereof, and Fuel Cell System - A hydrogen generation device of the present includes: a reforming unit for steam-reforming raw material containing at least carbon atoms and hydrogen atoms to generate a hydrogen-containing gas; a raw material supply unit for supplying a raw material to the reforming unit; a steam generation unit for supplying steam to the reforming unit, a steam generation unit temperature detection unit for detecting the temperature of the steam generation unit; a heating unit for supplying a combustion gas for successively heating the reforming unit and the steam generation unit by heat transfer, and a control unit. The control unit controls a raw material supply amount from the raw material supply unit and a water supply amount from a water supply unit and controls one of the amount of the air to the heating unit, the amount of a fuel to the heating unit, and the amount of the raw material to the reforming unit so that no water remains in the steam generation unit according to the detected temperature from the steam generation unit temperature detection unit. Thus, it is possible to operate the hydrogen generation device without leaving water in the steam generating unit and to provide a hydrogen generation device operation method having a high reliability and economy and a hydrogen generation device using the same as well as a fuel cell generation system using the hydrogen generation device. | 11-13-2008 |
