The present invention relates to a manifold having a leakage prevention unit for blocking the leakage of an electrolyte solution, an integrated complex electrode cell and a redox flow battery including the same. By having a first leakage prevention unit and a second leakage prevention unit, the electrolyte solution can be prevented from leaking through though-holes, or permeating into through-holes on the other side after infiltrating between gaskets. Thereby, the lifespan of the battery can be maintained and charge-discharge efficiency and energy efficiency can be prevented from decreasing by the increase in charging time or decrease in discharging time.
