This patent describes a rechargeable high temperature electrochemical power storage cell which comprises a cell housing divided by a separator into a pair of electrode compartments, one of which contains an anode substance and the other of which contains an active cathode substance and an electrolyte. The anode substance and electrolyte being liquid at the operating temperature of the cell, the separator separating the anode substance from the electrolyte and permitting the anode substance to pass from the anode compartment into the cathode compartment in ionic form, each of the compartments being divided into two communicating chambers, namely a gas chamber which contains an inert gas an and electrode chamber which contains a liquid at the operating temperature of the cell, a wall of each electrode chamber being provided by the separator and each electrode chamber having a closable outlet to the exterior of the cell, the cell having an operative attitude in which each closable outlet emerges from the associated electrode chamber at a level which permits any gas under pressure above a liquid in the chamber to be bled from the chamber, and in which operative attitude the communications between each electrode chamber and the associated gas chamber at a level spaced below the top of the associated gas chamber.
