Abstract: Disclosed is a hydrogen generator that prevents the reformate water from bypassing the evaporator in a hydrogen generator, and the occurrence of sudden temperature changes within an evaporation flow path. The hydrogen generator comprises: an evaporator that produces a mixed gas by mixing a raw material gas containing methane with water vapor; a reformer that changes the mixed gas into a hydrogen-containing gas through a steam reforming reaction; and a combustor that supplies heat to the evaporator and the reformer. The evaporator comprises: an inner cylinder; an outer cylinder enclosing the inner cylinder; and a middle cylinder that is inserted between the inner cylinder and the outer cylinder, and that defines a helical flow path between the inner cylinder and the outer cylinder, through which water supplied from the outside flows. On the inner peripheral surface and the outer peripheral surface of the middle cylinder, helical projections and recesses are integrally formed at the front and back, the top surface of the projections on the inner peripheral surface of the middle cylinder come into contact with the outer peripheral surface of the inner cylinder, and the top surface of the projections on the outer peripheral surface of the middle cylinder come into contact with the inner peripheral surface of the outer cylinder.

Abstract: An object of the present invention is to provide a fuel processor that can reduce reforming catalyst deterioration caused by thermal deformation of a structure. The fuel processor includes a reformer 8 that is fed with fuel gas 70 to refine hydrogen-rich reformed gas 73 by a reaction of a reforming catalyst 7. A plurality of partition plates 20 for dividing the reforming catalyst 7 are provided in a space filled with the reforming catalyst 7 between an internal cylinder 18 and an external cylinder 19. All the partition plates 20 are cantilevered from the external cylinder, preventing the partition plates 20 from coming into contact with each other in temperature variations. This can reduce deterioration such as crushing or powdering that is caused by a compressive stress of the reforming catalyst 7.

Abstract: A hydrogen generator (1) includes: a tubular reformer (2) configured to generate a hydrogen-containing gas by a reforming reaction using a material gas; a CO reducer (4) configured to reduce carbon monoxide contained in the hydrogen-containing gas generated in the reformer; a tubular hydro-desulfurizer (3) provided at an outer periphery of the reformer and configured to remove a sulfur compound contained in the material gas; and a material gas supply passage(331) through which the material gas to be supplied to the hydro-desulfurizer flows. The material gas supply passage is configured to perform heat exchange with the CO reducer, and a material gas inlet port (341) of the hydro-desulfurizer is provided at an end surface closer to the CO reducer.

Abstract: A hydrogen generation apparatus according to the present invention includes: a first desulfurizer (1); a second desulfurizer (2); a reformer (3) configured to generate a hydrogen-containing reformed gas from a raw material gas from which sulfur has been removed by at least one of the first desulfurizer (1) and the second desulfurizer (2); and a recycle passage (6) through which a part of the reformed gas generated by the reformer (3) is mixed into the raw material gas that is to be supplied to the second desulfurizer (2). The hydrogen generation apparatus is configured such that after installation or maintenance of the hydrogen generation apparatus, the raw material gas is supplied to the reformer (3) through the first desulfurizer (1) until a catalyst in the second desulfurizer (2) is activated by a mixed gas of the reformed gas supplied through the recycle passage (6) and the raw material gas, and after the catalyst in the second desulfurizer (2) is activated, the raw material gas is supplied to the reformer (3) through the second desulfurizer (2).
