Improvement of performance in redox flow batteries for PV systems

Abstract A redox flow battery (RFB) is a new type battery. A new piping sytem to improve the performance of RFBs for PV systems is introduced. In this new system, the piping for the electrolytes also connects each stack in series just like the electric circuit. In this system, the leak current through the electrolytes in the piping between each stack is suppressed. This system is called multitank system because it has many minitanks between each stack. It is clarified from the experimental and simulation results of the multitank system that this system improves the performance of RFBs.
