ABSTRACT:
A control device for a fuel cell including a transient state determination unit which determines whether changes in generated output of the fuel cell are within a predetermined range; a hydrogen purge detection unit which detects the presence/absence of a purge command to a hydrogen purge valve; a failure determination unit which determines, if the transient state determination unit determined that it is not a transient state, failure in the hydrogen purge valve based on an actual hydrogen pressure value at an inlet portion of the fuel cell and a target hydrogen pressure value, which is set in accordance with the presence/absence of the purge command detected by the hydrogen purge detection unit; and an alarm unit which generates an alarm when failure in the hydrogen purge valve is determined by the failure determination unit.
