An electrochemical cell for the electrolytic production of fluorine gas from molten KF -2HF electrolyte comprising: (1) a cell housing; (2) a current collector, said current collector having a hollow portion; (3) a first electrode used as a hydrogen generating cathode; (4) a second electrode used as a fluorine generating anode, wherein said anode of said electrode is comprised of a continuously vertical nongraphitic low-permeability carbon, wherein the surface of the anode consists of a plurality of parallel, substantially vertical channels disposed around the circumference of said anode, and; (5) an anode current carrier comprising: (a) a metal sleeve overlaying a portion of said anode and said hollow portion of said current collector, where the upper end of the anode and the lower end of the collector are axially aligned and abutted; and (b) a means for uniformly applying circumferential compression to said metal sleeve overlaying the contiguous and axially aligned and abutted portions of said anode and said current collector of the electrochemical cell to provide mechanical support for said anode and to provide electrical continuity between said anode and said current collector with the proviso that said portions of said anode and said current collector have approximately the same outer diameter, said current carrier and said portions of said anode and said current collector overlaid by said current carrier are wholly contained within said cell housing.
