Abstract

Egy elektrokémiai félcella, amely különösen klórnak alkáli-kloridvizes oldataiból elektrokémiai úton történő előállítására alkalmas,elektrolit befogadására szolgáló elektródteret (10) tartalmaz.Ezenkívül gáz befogadására szolgáló több gáztáska (20, 22) vanelrendezve. A gáztáskák (20, 22) az elektródtértől (10) gázdiffúzióselektród (36) révén vannak szétválasztva. Ezenkívül összekötő csatorna(26) van elrendezve, amelyen keresztül két gáztáska (20, 22) egymássalössze van kötve. Egy alul elhelyezkedő gáztáskában (20) lévőgázkibocsátó nyíláson (28) keresztül az összekötő csatornába (26)áramlik. Az összekötő csatornában (26) nyíl (46) irányában felfeléáramlik, és egy bebocsátó nyíláson (30) keresztül egy feletteelhelyezkedő gáztáskába (22) jut. Annak megakadályozása érdekében,hogy a gáztáskába (22) elektrolit (42) kerüljön, az összekötőcsatornában (26) a találmány szerint visszatartó elem (40) vanelrendezve. ÓAn electrochemical half-cell, which is particularly suitable for the electrochemical production of chlorine from aqueous alkali chloride solutions, contains an electrode space (10) for receiving electrolyte. In addition, several gas bags (20, 22) for receiving gas are arranged. The gas bags (20, 22) are separated from the electrode space (10) by a gas diffusion electrode (36). In addition, a connecting channel (26) is arranged through which two gas bags (20, 22) are interconnected. It flows into the connecting channel (26) through a gas release opening (28) in a gas bag (20) located below. It flows upwards in the direction of arrow (46) in the connecting channel (26) and enters an upper gas bag (22) through an inlet opening (30). In order to prevent electrolyte (42) from entering the gas bag (22), a retaining element (40) according to the invention is arranged in the connecting channel (26). HE
