OPERATING METHOD FOR VANADIUM REDOX FLOW BATTERY

摘要

PROBLEM TO BE SOLVED: To provide an operating method for a vanadium redox flow battery having a large rate of solution utilization and giving a high output. SOLUTION: The operating method is for the vanadium redox flow battery of high output operated in such a manner that an electrolytic solution is fed in circulation to an electrode and the discharge current density per unit area of electrode is made between 0.20 and 0.55 A/cm<2> , wherein the solution feeding amount per unit area of electrode of the electrolytic solution immediately before attaining the predetermined discharge ending voltage is made over 0.3 cc/ min×cm<2> .
