Sulfuric acid thermoelectrochemical system and method
This patent describes a thermoelectrochemical system for generating an electrical current including: an electrochemical cell having a cathode compartment and an anode compartment, the compartments having a common ion permeable separation wall; a cathode comprising lead oxide and an anode comprising lead sulfate located within their respective compartments, the cathode and anode being connectable externally of the cell for generation of the electrical current therebetween; a cathode solution comprising concentrated sulfuric acid located in the cathode compartment and in contract with the cathode wherein water is generated or collected and sulfuric acid is consumed at the cathode during generation of the electrical current; an anode solution comprising an aqueous buffer solution of sodium sulfate and sodium bisulfate located in the anode compartment and in contact with the anode wherein sodium bisulfate is generated and sodium sulfate is consumed at the anode during generation of the electrical current.
