Abstract (en)

Provided is a method for producing fluorine gas, capable of suppressing clogging of pipes and valves with mist. Fluorine gas is produced by a method including electrolyzing an electrolyte in an electrolytic cell, measuring an electric energy accumulated after the electrolyte is placed in the electrolytic cell, and the electrolyzing is started, and sending a fluid generated in the inside of the electrolytic cell in the electrolyzing the electrolyte, from the inside to the outside of the electrolytic cell through a flow path. In the sending, the flow path in which the fluid flows is switched in accordance with the electric energy measured in the measuring an electric energy, such that the fluid is sent to a first flow path that sends the fluid from the inside of the electrolytic cell to a first outside when the electric energy measured in the measuring an electric energy is not less than a predetermined reference value, or the fluid is sent to a second flow path that sends the fluid from the inside of the electrolytic cell to a second outside when the electric energy is less than the predetermined reference value. The predetermined reference value is 40 kAh or more relative to 1,000 L of the electrolyte.
