description A redox flow battery according to the present invention comprises a battery cell or a stack and an electrolyte tank in a battery module, and means for replacing a pump to transport an electrolyte to the battery cell or tack is applied to each battery module so that occurrence of shunt current can be dramatically reduced. Also, by providing the electrolyte tank for each battery module, a transporting path of the electrolyte can be drastically reduced. Instead of providing the pump for each module for transporting the electrolyte, a fluid control unit using pressure is provided to save power required for driving the pump and increase the efficiency of the battery. 본 발명에 따른 레독스 흐름전지는 전지모듈 내에 전지셀 또는 스택과 전해액탱크를 구비하고, 전해액을 전지셀 또는 스택으로 운반하기 위해 펌프를 대체하는 수단을 각 전지모듈별로 적용함으로써 분로전류의 발생을 획기적으로 줄일 수 있다. 또한 전지모듈별로 전해액탱크를 구비함으로써 전해액의 이송경로를 비약적으로 줄일 수 있으며, 전해액을 운송하기 위해 각 모듈별로 펌프를 구비하는 대신 압력을 이용한 유체제어부를 구비하여 펌프 구동에 필요한 동력을 절약하고, 전지의 효율을 높일 수 있다.
