<P>PROBLEM TO BE SOLVED: To provide an apparatus for generating hydrogen where starting time can be shortened by rapid temperature rising in an initial stage and where CO concentration can be sufficiently lowered. <P>SOLUTION: The apparatus for generating hydrogen where a hydrogen-rich reformed gas is produced by reforming a hydrocarbon-based gas comprises a reforming portion 1 where the inner combustion and the reforming reaction of a hydrocarbon gas are performed by bringing the hydrocarbon-based gas together with an oxidation gas and steam into a catalytic reaction with a catalyst, a CO modifying portion 2 to reduce CO in the reformed gas obtained at the reforming portion 1 by CO conversion to hydrogen, a CO selective oxidation portion 3 to reduce residual CO in the reformed gas discharged from the CO modifying portion 2 by oxidation and a first heat exchanger 11 to cool heat generated by a CO selective oxidation reaction at the CO selective oxidation portion 3 with the oxidation gas. The oxidation gas heated in the first heat exchanger 11 is introduced into the reforming portion 1 as the oxidation gas for inner combustion at the reforming portion 1. <P>COPYRIGHT: (C)2008,JPO&INPIT |
