To provide a fluorine gas generation device that effectively uses a coolant used for purification of fluorine gas.
The fluorine gas generation device includes: an electrolytic cell 1 having a first gas chamber 11a where a main product gas essentially comprising fluorine gas generated on an anode 7 immersed in a molten salt is introduced, and a second gas chamber 12a where a byproduct gas essentially comprising hydrogen gas generated on a cathode 8 immersed in the molten salt is introduced, both chambers separated and segmented on the liquid surface of the molten salt; and a purifying device 16 for purifying the fluorine gas by solidifying and collecting hydrogen fluoride gas which is vaporized from the molten salt in the electrolytic cell 1 and mixed into the main product gas generated from the anode 7, by use of a coolant. The coolant used for solidifying the hydrogen fluoride gas in the purifying device 16 and then discharged is reused as a utility gas to be used in every predetermined part of the fluorine gas generating device 100.
