| 摘要 |
A redox flow battery (1) in which a positive electrode electrolyte stored in a positive electrode tank (106) and a negative electrode electrolyte stored in a negative electrode tank (107) are supplied to a battery element (100) to charge and discharge the battery is provided, the positive electrode electrolyte in the redox flow battery (1) containing a Mn ion as a positive electrode active material, the negative electrode electrolyte containing at least one of a Ti ion, a V ion, and a Cr ion as a negative electrode active material, in which the redox flow battery (1) includes a negative-electrode-side introduction duct (10) in communication with inside of the negative electrode tank (107) from outside thereof, for introducing oxidizing gas into the negative electrode tank (107), and a supply mechanism (11) for supplying the oxidizing gas into the negative electrode tank (107) via the negative-electrode-side introduction duct (10). |
