  • Unit cell for redox flow battery, for reducing pressure drop caused by electrolyte flow in stack
    Patent number: 11038180
    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.

  • Bipolar plate-electrode assembly using thermoplastic resin and manufacturing method thereof
    Patent number: 10741851
    Abstract: Provided is a bipolar plate-electrode assembly used in a redox flow battery stack, in which a bipolar plate (140) is made of a thermoplastic resin, electrodes (170A, 170B) disposed on both sides of the bipolar plate are thermally compressed at a central portion of the bipolar plate so as to be permeated into the bipolar plate, the size of the bipolar plate is larger than that of the electrodes, and fiber mats (150A, 150B) are hot-pressed so as to be permeated in an periphery (141) the bipolar plate which is a larger area than the electrodes.
