PROBLEM TO BE SOLVED: To prevent deterioration of a fuel cell by avoiding shut-down of the fuel cell caused by an overload state of the fuel cell during an independent power generation operation of a fuel cell system.SOLUTION: During an independent power generation operation for generating power in a fuel cell 11a and supplying only power from a power conversion device 12 in the case where power transmission of a system power source 30 is stopped, when power consumption of a second load device 18 calculated from at least either a current or a voltage of the second load device 18 detected by a sensor 12a is equal to or higher than a predetermined value, a fuel cell control device 19 of a fuel cell system determines an overload state of the fuel cell 11a (step S114) and, when the overload state of the fuel cell 11a is determined in the step S114, the fuel cell control device 19 performs control for causing a reporting device to report the overload state of the fuel cell 11a (step S122). |
