Abstract: An operation mode of a secondary battery (BAT) is determined based on state of charge of BAT. A power generation provisional command value of fuel cell (FC) at time i is determined to maximize efficiency of FC based on system required power and state of charge of BAT at time i. An intermittent ON/OFF state at time i is determined such that switching of intermittent operation of FC is not continuous based on operation mode of BAT, the power generation provisional command value, and the system required power at time i, and an intermittent ON/OFF state at time (i?1). Further, when intermittent ON is determined at time i, the FC is stopped, and when intermittent OFF is determined at time i, a larger one is output, as the power generation command value for the FC at time i, between the power generation provisional command value and an intermittent OFF threshold.
