Abstract

Die Erfindung beschäftigt sich mit dem Problem der Befeuchtung einer PEM bzw. einer MEA. Es wird eine Elektrodenplatte für eine PEM-Brennstoffzelle vorgeschlagen, die wenigstens einen auf ihr integrierten Bereich für die Befeuchtung eines Reaktandenstroms aufweist. Ferner wird eine PEM-Brennstoffzelle vorgeschlagen, die diese Elektrodenplatte aufweist, sowie ein PEM-Brennstoffzellenstapel, der diese PEM-Brennstoffzellen aufweist. Außerdem wird ein Verfahren zur Befeuchtung von Reaktandenströmen für PEM-Brennstoffzellen vorgeschlagen, bei dem Reaktanden nach Eintritt in die Brennstoffzelle und vor Eintritt in einen Verteilungsbereich in einem Befeuchtungsbereich befeuchtet werden. Ferner wird ein Verfahren zum Be­feuchten einer PEM einer PEM-Brennstoffzelle vorgeschlagen, sowie ein Verfahren zum Betreiben von PEM-Brennstoffzellen. Die Erfindung ermöglicht v.a. die Durchführung der Befeuchtung auf einfache und wirkungsvolle Weise in einer PEM-Brennstoffzelle. Dadurch können beispielsweise Volumen und Gewicht reduziert werden.
