Abstract

Die Erfindung betrifft einen elektrochemischen Zellenstapel (Stack), vorzugsweise einen Zellenstapel für Membranbrennstoff- oder Membranelektrolyse-Zellen, gebildet aus mehreren parallel oder hintereinander geschalteten Einzelzellen, wobei alle Kathodenseiten der Einzelzellen und alle Anodenseiten der Einzelzellen in Taschen angeordnet sind, die durch eine mäanderförmig gefaltete Elektrolytschicht gebildet werden und die an ihren oberen und unteren Stirnflächen verschlossen sind. Die Einzelzellen sind in bekannter Weise aus Elektroden mit Stromab- ­bzw. Zuleitern sowie gegebenenfalls Backing und Strömungsverteilern auf beiden Seiten der Elektrolytschicht aufgebaut, wobei die einzelnen Stromab- bzw. Zuleiter elektrisch so verschaltet werden, dass sich eine Reihen- oder Parallelschaltung ergibt. Dann kann Zu- oder Abfuhr des Anodenfluids bzw. des Kathodenfluids für alle zur Anoden- ­bzw. Kathodenseite offenen Taschen des Anoden- bzw. Kathodenraums jeweils gemeinsam erfolgen, ohne dass die in einem Parallelplattenstapel übliche Einzelverteilung und Abdichtung aufeinander folgender Zellen erforderlich wäre. Stattdessen wird die Abdichtung zwischen Anoden- und Kathodenraum durch die gefaltete Elektrolytschicht und die beiden stirnseitigen Abdichtungen gewährleistet.
