Abstract
The invention provides a high temperature electrochemical cell having an anode and a cathode separated by a separator. The cell has a housing divided by the separator into two cell compartments for the anode and cathode, each of which compartments contains liquid at the cell operating temperature, and has a gas space therein above the liquid, containing an inert gas. The cell compartments are in communication with each other, e.g. by passage, and are otherwise sealed. This communication is above the levels of the liquid in the compartments at all stages of charge of the cell.
