Abstract

Die Erfindung beschreibt eine elektrochemische Halbzelle, insbesondere zur Elektrolyse von wässrigen Lösungen von Chlorwasserstoff, wenigstens umfassend einen Gasraum, wobei der Gasraum eine Gaszuführung und eine Gasabführung sowie einen Flüssigkeitsauslass aufweist, und eine Gasdiffusionselektrode, welche auf einem elektrisch leitenden Stromverteiler aufliegt und den Stromverteiler elektrisch leitend kontaktiert, wobei der Stromverteiler eine Freifläche im Bereich von 5 bis 65 %, bevorzugt von 10 bis 60 %, insbesondere bevorzugt von 15 bis 50 %, bezogen auf die Gesamtfläche des Stromverteilers und eine Dicke von 0,3 mm bis 5 mm, bevorzugt von 0,35 bis 0,6 mm, aufweist.
