Beschreibung
Zusammenfassung:	A fuel cell system includes a coolant control valve to switch a flowing path of a coolant passing through a fluid passage connected to a fuel cell stack, and a controller to control a valve opening amount of the coolant control valve while performing a start sequence previously defined, when a condition for normal start of the fuel cell stack is satisfied, and the coolant control valve is formed by integrating a first valve to switch a flowing path of a coolant flowing into a first pump with a second valve to switch a flowing path of a coolant pumped by the first pump.
