ABSTRACT:
The invention provides a method and apparatus for current control in gas generators capable of generating a fluorine or fluoride gas by and in which the electrolysis can be maintained in an optimum condition, stable operation is possible and no manpower is demanded. According to the method of current control in gas generators for generating a fluorine or fluoride gas by electrolysis of an electrolytic bath5comprising a hydrogen fluoride-containing mixed molten salt using a carbon electrode as the anode4a, the range of voltage fluctuation between the cathode4band anode4aas occurring when a certain current is applied to the gas generator is measured, and current application is continued while varying the current amount to be applied according to the voltage fluctuation range.
