Abstract
A fuel cell system includes a fuel cell stack, an oxidizing gas supply system, a cooling medium circulation pump, a stack temperature acquisition unit, and a control unit. After a first time point when a change in an acquisition temperature turns from downward to upward after the change in the acquisition temperature turns from upward to downward for the first time after the start of the warm-up operation processing, the control unit sets a decrease speed in cases of decreasing a rotational speed of the cooling medium circulation pump to a smaller value than a value set before the first time point.
