Abstract:
An electrochemical cell for the production of fluorine, comprising:(1) a cell housing;(2) a KF.multidot.2HF electrolyte;(3) a cathode, in contact with the electrolyte, at which hydrogen gas is generated;(4) an anode assembly comprising:(a) a carbon anode, in contact with the electrolyte, at which fluorine gas is generated;(b) an internal metal conductor, positioned in a centrally located internal channel, wherein the internal metal conductor is not in contact with the electrolyte and extends from the top of the carbon anode to below the electrolyte;(c) an outer gas separator positioned equidistant between the anode assembly and the cathode; and(d) an anode hanger abutted to the carbon anode; mechanically and electrically connected to the carbon anode using a sleeve and compression means to hold the sleeve, anode hanger and carbon anode in alignment;(5) a means for supplying current to the cathode and the anode; and(6) means for removing the generated fluorine gas and a means for removing the generated hydrogen gas.
