Abstract
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.
