REDOX FLOW BATTERY

A redox flow battery according to the present invention includes a battery module having, therein, battery cells or a stack and an electrolyte tank, and applies, to each battery module, a means for replacing a pump so as to transport the electrolyte to the battery cell or the stack, thereby significantly reducing the occurrence of a shunt current. In addition, a transfer path of the electrolyte can be rapidly reduced by providing an electrolyte tank for each battery module, and the power, which is required for operating the pump, can be saved by providing a fluid control unit using pressure, instead of providing the pump for each module, in order to transport the electrolyte, thereby enhancing battery efficiency.
