PROBLEM TO BE SOLVED: To enable reforming efficiency to be improved.SOLUTION: In an embodiment, a reformer is equipped with: a reforming unit 1 of generating a hydrogen-rich gas by introducing a mixed gas of hydrocarbon-based fuel and steam; an evaporator 2 of generating steam to be used for generating the mixed gas; a preheater 3 of heating the mixed gas by exchanging heat with the hydrogen-rich gas generated from the reformer 1; and a low temperature reaction unit 4 having a function to reduce carbon monoxide in the hydrogen-rich gas derived at least from the preheater 3 by a chemical reaction. The evaporator 2, the reformer 1 and the preheater 3 are arranged in this order, and each is provided with a heat-insulating material therearound. A width of the reformer 1, in a second direction perpendicular to a first direction being the arrangement direction, is smaller than at least one of the width of the evaporator 2 and the width of the preheater 3 in the second direction. |
