Abstract
Provided is a redox flow battery stack comprising: an ion-exchange membrane (1000); two flow frames (2000A, 2000B) disposed on both sides of the ion-exchange membrane (1000), respectively; two bipolar plates (4000A, 4000B) disposed outside the flow frames (2000A, 2000B), respectively; and electrodes disposed in cavities inside outer frames of the flow frames (2000A, 2000B), respectively, in which at least two electrodes are disposed in the flow frames, respectively, and at least three furrows in which the electrolyte flows are formed between electrodes or between the electrode and the outer frame in the flow frame.
