<P>PROBLEM TO BE SOLVED: To provide a system for producing hydrogen, which exhibits improved thermal efficiency and in which the problem related to the waste water treatment is solved and apparatus itself can be made compact; and to provide a method for producing hydrogen. <P>SOLUTION: In a hydrogen producing system, which produces hydrogen by performing steam reforming reaction using hydrocarbons or oxygen-containing hydrocarbons as raw materials in a hydrogen separation-type reformer 1 having a hydrogen permeation section partitioned by a hydrogen separation membrane 5 in a reaction tube filled with a reforming catalyst 3 and a combustion gas passage at the outside of the reaction tube, a pressure reducing means 7 for reducing the pressure of an exhaust gas 6 of the reformer 1 and an exhaust gas reformer 8 for reforming the exhaust gas 6 having passed through the pressure reducing means 7 are provided, and the exhaust gas 6 having passed through the exhaust gas reformer 8 is burnt by a combustor 10 of the hydrogen separation-type reformer 1. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
