<P>PROBLEM TO BE SOLVED: To provide a hydrogen manufacturing device capable of preventing condensed water from reaching a heating means, even if the condensed water comes from vapor contained in the offgas. <P>SOLUTION: The device is provided with a reforming part 1 generating hydrogen-rich reformed gas by vapor reforming reaction of hydrocarbon system fuel and water, a heating means 3 heating the reforming part 1 by combusting offgas returned from a fuel cell 2 supplied with reformed gas, a fuel gas supply tube 4 supplying offgas to the hating means 3, a combustion air supply tube 5 supplying air for combustion to the heating means 3, and a water rest part 6 fitted on the way from the fuel gas supply tube 4 for storing condensed water contained in the offgas. The condensed water contained in the offgas passing through the fuel gas supply tube 4 can be trapped and stored in the water rest part 6, so that it can be prevented from reaching the heating means 3. <P>COPYRIGHT: (C)2008,JPO&INPIT |
