Electrochemical cells having a first central anode, a second anode in the form of a concentric annular ring disposed around the central anode, a cathode, also in the form of a concentric annular ring, positioned between the first and second anodes, but not in mechanical contact therewith, and an electrolytic solution between and in contact with the anodes and cathode. The central anode can be in the form of a cylindrical rod or, preferably, a concentric annular ring.
