REDOX-FLOW BATTERY OPERATION METHOD AND REDOX-FLOW BATTERY

摘要

A redox-flow battery operation method wherein a positive-electrode circulation mechanism is used to circulate a positive-electrode electrolyte solution and a negative-electrode circulation mechanism is used to circulate a negative-electrode electrolyte solution in a cell stack that is formed by laminating a plurality of battery cells that have a positive electrode, a negative electrode, and a separator membrane. When the positive-electrode electrolyte solution and the negative-electrode electrolyte solution are circulated in the cell stack, this redox-flow battery operation method maintains a pressure differential wherein the pressure that acts on the separator membranes from the positive-electrode electrolyte solution is higher than the pressure from the negative-electrode electrolyte solution.
