OSTI ID:7317560
A sodium-sulfur cell is provided having a ceramic spacer means disposed in the liquid sulfur compartment to provide a region substantially free from cathodic reactions. The spacer means is disposed adjacent to materials likely to be adversely affected by the cathodic reactions, such as glass seals used to join the solid electrolyte to a ceramic support member, or a metallic end cap provided to close the liquid sulfur compartment. 3 figures.
