ABSTRACT:
In a reactive metal-water electrochemical cell, a configuration utilizing waste heat and evolved hydrogen gas for pumping electrolyte through the cell. More particularly, the cell is in a vertical, hollow tubular configuration with the reactive anode being bonded to the interior surface of the tube casing and a coiled metal screen cathode being positioned within the tubular cell and containing the anode over essentially its full working surface. As the anode is consumed in operation, by reaction with an aqueous electrolyte filling the interior cavity of the tubular configuration, the coil configuration of the cathode forces it to expand and maintain contact with the anode. During operation, evolved waste heat and gas cause a flow of electrolyte through the interior of the cell.
