Abstract

Eine elektrochemische Halbzelle weist eine Gasdiffusionselektrode (10) auf, welche einen Gasraum (11) von einem Elektrodenraum zur Aufnahme eines Elektrolyt trennt. Der Gasraum (11) weist eine Gas-/Flüssigkeitsabführeinrichtung in Form einer Öffnung (26) zum Abführen von Gas und/oder Flüssigkeit aus dem Gasraum (11) auf. Um ein Benetzen der Gasdiffusionselektrode (10) zu vermeiden, ist die Öffnung (26) versetzt unterhalb einer elektrochemisch aktiven Fläche der Gasdiffusionselektrode (10), d.h. unterhalb einer Unterkante (28), angeordnet.
