A carbon anode for a fluorine-producing cell is doped with a very fine dispersion of one or more transition metals, preferably nickel, vanadium and/or cobalt. The transition metal may be dispersed within the particles and/or the binder and is conveniently introduced in the form of an organic complex

A carbon anode for a fluorine-producing cell is doped with a very fine dispersion of one or more transition metals, preferably nickel, vanadium and/or cobalt. The transition metal may be dispersed within the particles and/or the binder and is conveniently introduced in the form of an organic complex of the transition metal which decomposes during heat treatment of the consolidated mass of particles and binder.

In an electrolytic cell for the production of fluorine, said cell comprising a molten fluorine-containing salt electrolyte and means, including a carbon anode, for providing electrolysis of said electrolyte to generate fluorine, the improvement wherein the carbon anode comprises a consolidated mass

In an electrolytic cell for the production of fluorine, said cell comprising a molten fluorine-containing salt electrolyte and means, including a carbon anode, for providing electrolysis of said electrolyte to generate fluorine, the improvement wherein the carbon anode comprises a consolidated mass consisting essentially of carbon particles, and less 1.0 atoms % of a transition metal, at least a substantial part of the transition metal being dispersed within the consolidated mass as a very fine dispersion of metal sites having diameters no greater than 1×10-9 meters, to thereby inhibit anode over-voltage during operation of the cell.
