Abstract: A redox flow battery includes a positive-side electrode tank that stores an electrolytic solution to be circulated to a positive electrode chamber in which a positive electrode is accommodated; and a negative-side electrode tank that stores an electrolytic solution to be circulated to a negative electrode chamber in which a negative electrode is accommodated. Each electrolytic solution contains an active material and a mediator, and the active material is solid in each electrolytic solution. An electrolyte concentration in each electrolytic solution is adjusted such that a potential difference between an equilibrium potential of the active material and an equilibrium potential of the mediator is equal to or less than a predetermined potential difference.
