Abstract

Eine Polymerelektrolytmembran-Brennstoffzelle, bei der in mindestens einem ihrer Fluidräume wenigstens eine Trennwand vorgesehen ist, die in dem Fluidraum zumindest einen weiteren Raum abtrennt, wobei der zumindest eine weitere, abgetrennte Raum an wenigstens einer Stelle eine fluidische Verbindung zu einem angrenzenden Anoden- oder Kathodenraum aufweist. die Polymerelektrolytmembran-Brennstoffzelle kann mit wenig oder gar nicht befeuchteten Reaktionsstoffen betrieben werden, ohne dass ihre Polymerelektrolytmembran dabei austrocknet.
