57	Abstract	AB	Ein Verfahren zum Starten eines kalten oder gefrorenen Brennstoffzellenstapels so effizient und schnell wie möglich in einer Fahrzeuganwendung basiert auf einem Ladezustand einer ersten Leistungsquelle, wie einer Hochspannungsbatterie. Ein Leistungsfluss zwischen der ersten Leistungsquelle und dem Brennstoffzellensystems wird in Verbindung mit einem spezifischen Lastplan und parallelen Steueralgorithmen koordiniert, um die erforderliche Startzeit zu minimieren und eine Systemaufwärmung zu optimieren.
