The present invention relates to a redox flow battery stack which is capable of reducing pressure drop. According to the present invention, provided is the redox flow battery stack comprising: an ion-exchange membrane (1000); two movable plates (2000A, 2000B) disposed on both sides of the ion-exchange membrane (1000); two separation plates (4000A, 4000B) disposed outside the movable plates (2000A, 2000B); and electrodes disposed in cavities inside outer frames of the movable plates (2000A, 2000B); wherein the electrodes disposed on the movable plates are at least two in number, and at least three furrows through which electrolyte flows are formed between the electrode and the electrode or between the electrode and outer frame in each of the movable plates.
