Zusammenfassung:	When a stop time is defined as a time from an operation stop to an operation restart of an intermittent operation of circulation pump (4) which circulates cooling water through circulation channel (3) for heat exchange between the cooling water and fuel cell (2), controller (15) intermittently operates circulation pump (4) during a start of fuel cell (2) and electricity generation of fuel cell (2), such that a second stop time corresponding to a stop time of the intermittent operation during electricity generation by fuel cell (2) is shorter than a first stop time corresponding to a stop time of the intermittent operation during the start of fuel cell (2). Accordingly, air remaining in circulation channel (3) through which cooling water circulates for heat exchange with fuel cell (2) can be reliably removed, and thermal deterioration of constituent elements of fuel cell (2) can be prevented.
