Abstract

Die Erfindung betrifft einen elektrochemischer Zellenstapel umfassend jeweils abwechselnd angeordnete Membran-Elektroden-Einheiten (3) und Separatorplatten (2, 2a) zur Zu- und Abführung dür das Reaktant- und Oxidant-Fluid, wobei durch einen Prägevorgang die eine Seite der Separatorplatte (2, 2a) eine Oberflächenstruktur und die andere Seite eine hierzu negative Oberflächenstruktur aufweist. Gemäß der Erfindung liegen sich beim Stapeln der Separatorplatten (2, 2a) jeweils eine Oberflächenstruktur einer Separatorplatte (2) einer korrespondierenden negativen Oberflächenstruktur der benachbarten Separatorplatte (2a) gegenüber.
