An electrolyzer for producing high purity nitrogen trifluoride(NF3) at high efficiency and low cost, which has an electrolyzer top plate cooling pipe that removes hydrofluoric acid(HF) generated during the electrolysis for producing nitrogen trifluoride, and a method of producing nitrogen trifluoride using the electrolyzer are provided. In an electrolyzer for producing nitrogen trifluoride(NF3) through molten salt electrolysis, the electrolyzer comprises an electrolyzer body(1), a fluorine resin coated bottom face(2), a fluorine resin coated separation plate(3), an electrolyte(4), a Ni anode(5), a Ni cathode(6), an anode connecting rod(7), a cathode connecting rod(8), a produced nitrogen trifluoride(NF3) outlet(9), a produced hydrogen(H2) outlet(10), an electrolyzer top plate(11), and a cooling pipe, wherein the cooling pipe includes an electrolyzer top plate cooling pipe(13). The electrolyzer top plate cooling pipe is a cooling system capable of controlling temperature of the electrolyzer top plate to 10 to 130 deg.C while proceeding the molten salt electrolysis. The electrolyzer further comprises an electrolyzer sidewall cooling pipe(12) in addition to the electrolyzer top plate cooling pipe to control temperature of the electrolyte to 100 to 130 deg.C during the molten salt electrolysis.
