Claim Text:
1. An electrolytic apparatus for producing nitrogen trifluoride by electrolyzing a hydrogen fluoride-containing molten salt electrolyte at an applied current density, which comprises: an electrolytic cell which is partitioned into one or more anode chambers and cathode chambers by one or more partition walls between each anode chamber and cathode chamber, wherein each anode chamber comprises one or more anodes comprising at least one inner surface and at least two outer surfaces arranged opposite to each other with the at least one inner surface arranged between the at least two outer surfaces, and each cathode chamber comprises one or more cathodes, wherein the anode chamber and the cathode chamber are configured such that any one of the one or more cathodes is adjacent to at least one of the outer surfaces of the one or more anodes and there is no cathode adjacent to the at least one inner surface of the one or more anodes; a molten salt electrolyte surrounding the one or more anodes and the one or more cathodes, at least one anode gas outlet for withdrawing gas from the anode chamber; and at least one cathode gas outlet for withdrawing gas from the cathode chamber.
