Abstract

This invention relates to electrodes for electrolytic cells. More particularly, this invention relates to electrodes for an electrolytic cell comprising: PA0 (a) means for supplying electric current; PA0 (b) a main current distributor; PA0 (c) rectangular-sectioned conductors having flat activated electrode faces and arranged standing upright, the ratio of the width to height of a cross-section being from about 1:5 to about 2:3; and PA0 (d) flat, rectangular-sectioned current distributors arranged perpendicularly to the conductors (c) and spaced from about 30 to about 150 mm apart, the ratio of the width to height of a cross-section being smaller than that for the cross-section of conductors (c), the ratio of free passage area to projected area in the zone of the conductors (c) being from about 20:30 to about 60:80 and conductors (c) being connected to current distributors (d), which are in turn connected to main current distributor (b).
