PROBLEM TO BE SOLVED: To provide a reformer configured to enable further reliable improvement of temperature equalization all over oxidizing catalyst and reforming catalyst.SOLUTION: This invention relates to a reformer for generating hydrogen by modifying a hydrogen-based fuel containing at least hydrogen as a constituent. The reformer includes a catalyst unit composed of reforming catalyst and oxidizing catalyst, and an exterior housing structure for housing the catalyst unit therein, which has an inlet part for taking in the hydrogen-based fuel together with air as a mixed gas from an upstream passage disposed upstream of the oxidizing catalyst, an outlet part for releasing a generated reformed gas to a downstream passage disposed downstream of the reforming catalyst, and an outer peripheral wall part for closing around the external perimeter of the reforming catalyst and the oxidizing catalyst. A heat insulating material is disposed on an inner wall of the outer peripheral wall part of the exterior housing structure, a metal tape is disposed on the external perimeter of the oxidizing catalyst and reforming catalyst, and a metal tape is disposed also between the oxidizing catalyst, reforming catalysts, and the heat insulating material. |
