Abstract

The electrolytic apparatus includes at least one set of cells housed in a stack of annular spacer frames, annular bearing surfaces of which indicate joint planes extending to the exterior of the stack of frames, and each equipped with electrode plates and a diaphragm which forms compartments containing each an electrolyte under pressure brought through at least one supply channel, the gases formed by electrolysis being discharged towards channels, and it is essentially characterized by the fact that with each joint plane extending to the exterior of the stack of frames there is associated at least one annular collector groove arranged in a bearing surface of a frame and associated with discharge means capable of discharging the electrolyte flowing through the said joint plane. The electrodes are bipolar and arranged with a structure reminiscent of the structure of a filterpress.
