Abstract
A hydrogen generation apparatus according to the present invention includes: a reformer configured to generate a hydrogen-containing gas through a reforming reaction; a combustor configured to heat the reformer; an air supply device configured to supply air to the combustor; a fuel supply device configured to supply a fuel to the combustor; a CO detector configured to detect a carbon monoxide concentration in a flue gas discharged from the combustor; and a controller configured to control at least one of the air supply device and the fuel supply device to increase an air ratio in the combustor such that the CO concentration in the flue gas increases, and then test the CO detector for abnormality.
