A hydrogen generation apparatusincludes: an evaporating part; a reforming reaction partA connected to the downstream side of the evaporating part; a carbon monoxide reducing partprovided downstream from the reforming reaction part; and a gas guiding partdisposed between the reforming reaction part and the carbon monoxide reducing part and configured to guide a gas that has passed through the reforming reaction part to the carbon monoxide reducing part. The evaporating part and the carbon monoxide reducing part are arranged to be adjacent to each other such that, at least, a part of the evaporating part and a part of the carbon monoxide reducing part are heat exchangeable with each other. The evaporating part is configured such that a heat exchange amount at a portion of the evaporating part, the portion corresponding to the carbon monoxide reducing part, is less than a heat exchange amount at a portion of the evaporating part, the portion not corresponding to the carbon monoxide reducing part.

Hydrogen generation apparatus and fuel cell power generation system

A hydrogen generation apparatus including: a first desulfurizer; a second desulfurizer; a reformer 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 and the second desulfurizer; and a recycle passage through which a part of the reformed gas generated by the reformer is mixed into the raw material gas to be supplied to the second desulfurizer. After installation or maintenance of the hydrogen generation apparatus, the raw material gas is supplied to the reformer through the first desulfurizer until a catalyst in the second desulfurizer is activated by a mixed gas of the reformed gas supplied through the recycle passage and the raw material gas, and after the catalyst in the second desulfurizer is activated, the raw material gas is supplied to the reformer through the second desulfurizer.
