Selection of systems for continuing development include 1 AsCl5-AsCl3 SbCl3-SbCl5 at 300600 2 HgCl2-HgCl Hg-HgCl at 480-950 and 3 CuCl2-CuCl TeCl2-TeCl4 at 480-950 K. The first system was operated as a miniature integrated unit. Regeneration was easily accomplished. Continuing development is directed toward larger systems and toward improvement of current density. Larger galvanic cells are also being developed for the second and third systems. Thermal regeneration of the latter 2 systems w s accomplished, but separation of the products was not inherent, as it was with the first ystem. A method of selective absorption in a molten KClNaCl eutectic is being developed. Breadboard models of the first and third systems are being developed. The system, CuCl2-CuCl SnCl2-SnCl4 at 480-2000 K, afforded promising galvanic cells, but require more severe material during regeneration. Author
