NOVELTY - The cell includes first and second chambers each chamber having a top closure with a positive contact through it and a cathode in electrical contact with the positive contact. There is a negative contact in electrical contact with a liquid metal anode. A gap is formed between the cathode and the liquid metal anode.    USE - For a self charging power supply for vehicles and construction equipment, and as a stationary power supply.    ADVANTAGE - The cell is portable, does not produce hydrogen, is minimally affected by climatic changes, is not consumed by the electrochemical reaction over time, and reduces the capital cost of a car over its lifetime.    DETAILED DESCRIPTION - A self-charging electrochemical cell (1) includes first and second chambers (2, 3) interconnected with tubing (5). Each chamber has a bottom. The tubing is controlled by a valve (6). Each chamber also has a top closure (4) with a positive contact through it and a cathode (8) in electrical contact with the positive contact. A microporous separator (10) is below the cathode supported by a holder mounted to the top closure, that also supports the cathode. A negative contact (25) is disposed through the chamber. There are also a gap (9), vents through the top closure of the chamber, and a thermowell (23). A set of stand pipes are in the first chamber, that connect the interior of the first chamber and the holder and the gap. There is a heater connection (24) in the second chamber. An inert gas cooling connection (60) is disposed through the top closure of the first chamber. At least one of the chambers further contains a liquid metal anode (7) at the bottom, a non-aqueous molten salt electrolyte (34) and a reduced metal (54). The negative contact is in electrical contact with the liquid metal anode. The gap is formed between the cathode and the liquid metal anode.
