Abstract
A fuel cell system is equipped with a fuel cell unit that is composed of a plurality of fuel cells including a first fuel cell and a second fuel cell, a first supply device and a second supply device that supply reactive gas to the first fuel cell and the second fuel cell respectively, and a control device that controls running of the first fuel cell and the second fuel cell and operation of the first supply device and the second supply device. The control device suspends electric power generation by the first fuel cell and drives the first supply device to hold an opening circuit voltage of the first fuel cell within a target range, and suspends electric power generation by the second fuel cell and stops driving the second supply device when an output P required of the fuel cell unit is equal to 0.
