Abstract
A fuel cell system includes a fuel cell stack in which a plurality of unit cells is stacked, a detection unit configured to detect a cell voltage of at least one of the unit cells, a converter configured to regulate an output current of the fuel cell stack, and a control device configured to control the converter. The control device executes current reduction processing for reducing the output current in a stepwise manner when the cell voltage detected by the detection unit is a negative voltage.
