<P>PROBLEM TO BE SOLVED: To provide a method by which, even when power generation characteristics of a fuel cell are deteriorated and a target output cannot be obtained, maximum output can be extracted within a range that the voltage of the fuel cell does not become lower than a lower limit voltage, and a situation is controlled such as that the supply amount of a reaction gas to a fuel cell stack becomes excessive. <P>SOLUTION: An output control part 44 restricts output of a fuel cell stack so that a stack voltage Vf may not be lower than the lower limit voltage established for the fuel cell stack, and a gas supply amount control part 43, when the stack voltage Vf reaches the lower limit voltage, controls the supply amount of a reaction gas to the fuel cell stack so that it may be the supply amount of the reaction gas corresponding to an actual extraction amount If detected by a current sensor 6. <P>COPYRIGHT: (C)2009,JPO&INPIT |
