Patent ID: 7351317

Claim:
An electrolytic cell for halogen gas production comprising: a housing of two half-shells made of electrically conductive material; anodic and cathodic electrodes ( 4 , 5 ) with an electrolytic membrane ( 6 ) arranged therebetween; at least one of said half-shells being provided with built-in components permitting a defined increase in the liquid level over the top edge of said electrolytic membrane ( 6 ), said built-in components forming an internal trough ( 7 ) having one major surface parallel to the electrolytic membrane ( 6 ) and spaced therefrom by a first interspace ( 9 , 14 ); a second interspace ( 10 , 15 ) inclined both outwards and upwards with respect to the horizontal plane as seen from said electrolytic membrane ( 6 ) being established between said trough ( 7 ) and the upper side of said at least one half-shell, said trough ( 7 ) having at least one opening communicating with said second interspace ( 10 , 15 ) and at least one outlet and the highest point of said second interspace ( 10 , 15 ) is located above the upper side of said electrolytic chamber ( 6 ).
