Included are: a basic operation plan creating sectionconfigured to create a basic operation plan based on durable years (e.g., 10 years) and a durable operating time (e.g., 40000 hours) of a fuel cell, such that the fuel cellis operated within the range of at least one of a first allowable operating time (e.g., 11 hours) per predetermined unit period (e.g., per day) and the number of durable start-ups (e.g., 4000 times) per predetermined unit period; a special operation plan creating sectionconfigured to create a special operation plan such that the fuel cellis operated within the range of at least one of a second allowable operating time (e.g., 20 hours) per predetermined unit period (e.g., per day) and a second allowable number of start-ups per predetermined unit period, the second allowable operating time being longer than the first allowable operating time, the second allowable number of start-ups being greater than the first allowable number of start-ups; an operation plan selecting sectionconfigured to select one of the basic operation plan and the special operation plan; and a fuel cell operating sectionconfigured to operate the fuel cellbased on the operation plan selected by the operation plan selecting section

Fuel cell operating method and fuel cell system

A hydrogen generator of the present invention includes a reformer () for generating a hydrogen-containing gas through a reforming reaction using a raw material; a combustor () for heating the reformer (); a combustion air supplier () for supplying combustion air to the combustor (); and an abnormality detector () for detecting an abnormality; and a controller () configured to control the combustion air supplier () such that the reformer () is cooled with a higher rate in an abnormal shut-down process executed after the abnormality detector () detects the abnormality, than in a normal shut-down process.
