Fluorine-generating electrolytic cells A fluorine generating electrolytic cell comprises a base (12) and cooling coils (24) for cooling the electrolyte, the cooling coils (24) being displaced from the base (12). A layer (10) of plastics material such as PTFE is disposed on the base (12) to electrically insulate the base (12) and the layer (10) is held against the base (12) by means (14-22) bridging the space between the cooling coils (24) and an upwardly presented face (9) of the layer (10). By using the cooling coils (24) in holding the insulating layer (10) in place, the need to make changes to the cell vessel is avoided and installation and removal of the layer (10) is relatively easy and inexpensive. In addition, by using an insulating layer (10), all of the electrolyte is molten with the advantage that a smaller temperature gradient through the depth of the electrolyte results, which leads to improvements in mass transfer.
