Abstract

Sofern eine PEM-Brennstoffzellenanlage mit Wasserstoff als Brenngas und mit Luft als Oxidans arbeitet, ist für einen schnellen Lastwechsel eine ausreichende Luftversorgung erforderlich. Dabei muss die zugeführte Luft befeuchtet werden. Sofern beim vorgegebenen niedrigen Druck keine ausreichende Befeuchtung der Luft vorliegt, wird erfindungsgemäß der Eingangsdruck so erhöht, dass die Befeuchtung durch Verschiebung der Wasserdampfpartialdruckkurve erreicht wird. Technisch wird dies durch eine Drosselklappe (15) in der Ausgangsleitung (18) des Brennstoffzellenstacks (10) erreicht, wobei gleichermaßen die Verdichterleistung für den Luftverdichter (35) geregelt wird.
