An electrolyzer cell is made up of a pair of electrodes (1,1') separated by a diaphragm (2). The diaphragm is sandwiched between a pair of frames (3,3') and generally includes its own frame (4). It is difficult to make frames sufficiently accurately for large cells (e.g. up to 2 m.sup.2). using conventional techniques of cutting the frame out from a sheet of material or by one-piece moulding. The present invention uses assembly of elongate frame components. Preferably they are joined together using dovetail joints (31,41), which ensure adequate sealing, and with the dovetails shifted from one frame to the next to ensure a more uniform pressing effect.
