Assignee: SAUDI ARABIAN OIL COMPANY
Field: Electrical machinery, apparatus, energy (Electrical engineering)
Classification: CPC H  Y | IPC H

Claim 15:
16. A method of producing electric current, comprising:
flowing an anolyte through a first channel in an electrochemical cell, wherein the first channel is formed in the space between an anode current collector and an ion exchange membrane;
flowing a catholyte through a second channel in the electrochemical cell, wherein the second channel is formed in the space between a cathode current collector and the ion exchange membrane, wherein the first channel and the second channel are separated by an ion exchange membrane, and wherein the catholyte comprises a mixed electrolyte comprising iron ions vanadium ions, 6.6 M Cl− ions, and 0.8 M SO42− ions;
flowing ions through the ion exchange membrane to oxidize the anolyte and reduce the catholyte; and
generating an electric current between the anode current collector and the cathode current collector.
