Abstract
Disclosed is a method of assembling a diaphragm cell having the electrodes of like polarity at a narrow pitch, and interleaved with electrodes of opposite polarity at a narrow interelectrode gap. The electrolytic cell is assembled while avoiding damage of the diaphragm during assembly. This is accomplished by drawing the diaphragm while maintaining a barrier between a pair of adjacent cathodes, avoiding bridging between adjacent cathode fingers. Additionally, where each anode is formed from a pair of metal sheets, the anode sheets are jointed together with leachable joint at the end of the sheets spaced from the anode unit.
