ABSTRACT:
An electrochemical power generation apparatus and methods of control thereof are described. The power source comprises one or more electrochemical cells having an anode and an oxygen or hydrogen peroxide depolarized cathode, a liquid electrolyte solution, electrolyte circulation means and an electrolyte container. The methods include varying the volumes of electrolyte in said container and in said battery cell so as to control the polarization and hence the cell output voltage of said anode and cathode. The anode is of the consumable-metal type, particularly aluminum. The method of varying the volume may be effected by expanding or collapsing a reversibly expansible pocket in said electrolyte container or by varying the rate of circulation of said electrolyte solution through said battery cell. Heat exchange apparatus may be included comprising a vacuum distillation means whereby impure ambient water or water trapped in the battery reaction product is converted into distilled water, preferably by utilizing the heat generated in said power source, said distilled water being in turn used to replenish the battery electrolyte and thereby increase the energy density of the battery.
