EXPANDERBAR ELEKTROD FOER ELEKTROLYTCELLER OCH FOERFARANDE FOER DESS MONTERING

An expandable electrode for use in an electrolytic cell of the diaphragm or membrane type and comprising a pair of electrode plates bridged along one edge of each plate, and located between the plates in a plane essentially perpendicular to the faces of the plates at least one spacing member which in profile is in the form of one or more substantially wedge-shaped sections and which is movable relative to the electrode plates, the electrode plates being provided with one or more transverse members which, upon movement of the spacing member relative to the plates, is or are engaged by the wedge-shaped sections(s) of the spacing member(s) to control the spacing between the electrode plates. The spacing member preferably comprises one or more double wedge-shaped sections and the electrode plates are preferably slotted plates, for example louvred plates.
