ABSTRACT:
A hydrogen generator of the invention includes: a reformer for generating a hydrogen-rich gas from a feed gas and water by a reaction using a reforming catalyst body and sending it out from an outlet port; a material feed system for feeding the feed gas to the reformer; a burner for supplying, to the reforming catalyst body, heat generated by mixing a fuel gas with air and burning it; and an air supply system for supplying air to the burner; wherein, when purging an interior of the reformer using the feed gas in shutting down the hydrogen generator, an amount of the air supplied is increased to put out a flame of the burner, and a purge gas sent out from the outlet port by the purging is mixed and diluted with the air in the burner and is discharged outside.
