Abstract
A fluorine gas generating apparatus generating a fluorine gas by electrolyzing hydrogen fluoride in molten salt, includes: an electrolytic cell including, above a liquid level of molten salt, a first gas chamber into which a product gas mainly containing the fluorine gas generated at an anode immersed in the molten salt and a second gas chamber separated from the first gas chamber into which a byproduct gas mainly containing a hydrogen gas generated at a cathode immersed in the molten salt; a hydrogen fluoride supply source retaining hydrogen fluoride to be replenished in the electrolytic cell; a refining device trapping a hydrogen fluoride gas evaporated from the molten salt in the electrolytic cell and mixed in the product gas generated from the anode to refine the fluorine gas; and a recovery facility conveying and recovering the hydrogen fluoride trapped in the refining device in the electrolytic cell or the hydrogen fluoride supply source.
