Abstract

Abstract AN ENERGY CONVERSION SYSTEM UTILIZING A PLURALITY OF ELECTROCHEMICAL CELLS EMPLOYING THE ZINC-OXYGEN ELECTROCHEMICAL COUPLE AND A CIRCULATING ALKALINE ELECTROLYTE WHICH IS PUMPED THROUGH THE CELLS TO REMOVE THE ZINC OXIDE REACTION PRODUCTS THEREFROM. A HIGH ELECTROLYTE FLOW RATE IS ACHIEVED THROUGH EACH OF THE CELLS, WHICH SCOURS THE ZINC OXIDE REACTION PRODUCTS FROM THE ZINC ANODES, BY PROVIDING A JET PUMP IN ASSOCIATION WITH EACH ELECTROCHEMICAL CELL UNIT. THE INDIVIDUAL JET PUMPS TRANSFORM A RELATIVELY LOW FLOW RATE OF HIGH PRESSURE LIQUID ELECTROLYTE FROM A HIGH PRESSURE PUMP INTO A SUBSTANTIALLY HIGHER CIRCULATION FLOW OF LOW PRESSURE ELECTROLYTE WITHIN EACH OF THE INDIVIDUAL ELECTROCHEMICAL CELLS.
