<P>PROBLEM TO BE SOLVED: To exercise control not to supply surplus power to an external load when power required to a fuel cell rapidly decreases during a low-efficient operation. <P>SOLUTION: When a power generation command value Pref to the fuel cell during the warming-up of the fuel cell by a low-efficient operation lower in the efficiency of power generation than the regular operation rapidly decreases, a fuel cell system raises an output voltage of the fuel cell to supply surplus power Ws corresponding to a difference between a power generation amount Pmes of the fuel cell and a power generation command value Pref to a capacitance component of the fuel cell for charging, and makes power (Pmes-Ws) supplied to an external load of the fuel cell coincide with the power generation command value Pref. <P>COPYRIGHT: (C)2009,JPO&INPIT |
