Ein in der vorliegenden Beschreibung offenbartes Brennstoffzellensystem umfasst einen Brennstoffzellenstapel, in dem eine Vielzahl von Einheitszellen gestapelt ist, und eine Steuerung, die Leerlaufvorgänge ausführt, um eine Ausgangsspannung des Brennstoffzellenstapels innerhalb eines vorbestimmten Leerlaufspannungsbereichs zu halten. Wenn eine vorbestimmte Rücksetzbedingung erfüllt ist, führt die Steuerung eine Rücksetzverarbeitung durch und kehrt zu den Leerlaufvorgängen zurück. Durch Ausführen der Rücksetzverarbeitung kann ein Fortschreiten einer Verschlechterung des Brennstoffzellenstapels unterdrückt werden. Ein Beispiel für die Rücksetzverarbeitung ist eine Verarbeitung zur Erhöhung einer Durchflussrate von Sauerstoff, der dem Brennstoffzellenstapel zugeführt wird, sodass sie größer als ein Höchstwert der Durchflussrate von Sauerstoffs ist, der dem Brennstoffzellenstapel während der Leerlaufvorgänge zugeführt wird. Ein Beispiel für die Rücksetzbedingung ist, dass eine vorbestimmte zulässige Leerlaufzeit ab Beginn der Leerlaufvorgänge verstreicht.
