PROBLEM TO BE SOLVED: To determine abnormality in a current sensor without incurring increase in cost and system size.SOLUTION: A fuel cell system control device includes: a first acquisition unit which acquires an output current value from the fuel cell by a first current sensor (step 102); a second acquisition unit (step 104) which acquires by a second current sensor an input current value for a power conversion unit which accepts as its input the output power of the fuel cell remaining after being supplied to an auxiliary machine and outputs it to an external load (step 104); a third acquisition unit which acquires a consumption current value within a predetermined range representing a current value consumed by the auxiliary machine previously stored in a storage unit (step 106); and a first determination unit which selects any two out of the current consumption values acquired by the first, the second, and the third acquisition units and compares an added or a subtracted result of these two values with the remainder to determine which of the first and the second current sensors is in an abnormal state (steps 108 to 114, 118, and 124). |
