Abstract

A method of shutting down a hydrogen generation apparatus for limiting degradation in a catalyst due to dew condensation at the time of shutdown is provided. The method of shutting down the hydrogen generation apparatus comprising, a combustor which supplies heat necessary to a reforming device, a first air supplier which supplies air to the combustor, a combustion exhaust gas path formed such that the combustion exhaust gas produced in the combustor makes heat exchange with the reforming device and then with a CO reducing device, and a controller which operates the first air supplier so that the temperature of the gas in the CO reducing device does not become equal to or lower than a dew point after shutdown of the combustion operation of the combustor and before a start of a purging operation to purge the interiors of the reforming device and the CO reducing device with a replacement gas.
