Abstract or Summary
  • The performance of solid metallic anodes on a solid electrolyte was determined experimentally and data on cell current, cell voltage, open-circuit cell potential, and cell energy are presented. Fifteen-mole percent calcia-stabilized zirconia was used as the electrolyte, a platinum-oxygen electrode was used as the cathode, and 1000° C was the operating temperature for all cells tested. The cells were built around a zirconia crucible, one-inch diameter and approximately 1/16 inch thick. The cathode was applied to the inside base of the crucible and the anode to the outside base. The anode was applied by a two-step process. First, a thin layer of the metal being studied was deposited by vacuum evaporation techniques, and second, the film was thickened using published electro-plating procedures. Attempts to fabricate cells using iron, nickel, cobalt, manganese, chromium, molybdenum, zirconium, yttrium, and a zirconium-yttrium mixture were successful only in the case of the first four elements. The cells were tested in a tube furnace with controlled cathodic and anodic atmospheres. The measured open-circuit voltages were in satisfactory agreement with the theoretical values determined from standard free energy data at 1000° C. All the cells behaved as secondary batteries, in that they could be recharged a number of times following the initial discharge. Data obtained for the iron and nickel cells established the reproducibility of the experimental procedures used in this work.
