摘要： PROBLEM TO BE SOLVED: To provide a hydrogen-producing device whose hydrogen partition walls have improved durability and which can produce highly pure hydrogen, by using a molded plate-like reforming catalyst. SOLUTION: The molded plate-like reforming catalyst 126 is preferably formed by carrying a Ni-based catalyst or the like on a metal such as stainless steel. A hydrogen-penetrating rectangular member 34 is provided with an inside wall 28 near to the plate-like reforming catalyst 126 and with an outside wall 32 near to the adjacent unit. The inside wall 28 and the outside wall 32 are formed from hydrogen- penetrating metal membranes, respectively. The unit is provided with a spacer 127 which is fixed to the plate-like reforming catalyst 126 and a hydrogen-penetrating rectangular member 34 by a welding method or the like, and is extended in the longitudinal direction of the hydrogen-penetrating rectangular member 34. Thereby, the spacer 127 is disposed between the hydrogen-penetrating rectangular member 34 and the plate-like reforming catalyst 126 of each unit, and when the unit is assembled in the second space, the spacer 127 of the outside wall 32 is also disposed between the outside wall 32 and the adjacent plate-like reforming catalyst 126. Thus, the damage of the metal membrane due to the contact with the plate-like reforming catalyst 126 is not caused.
