Abstract

PURPOSE:To improve the soluble rate of iron chloride and chromium chloride as active substances by including a specific amount or more of sulfuric acid and/or nitric acid in a hydrochloric acid electrolyte. CONSTITUTION:In a redox flow battery 2 in which a positive electrode 6 and a negative electrode 7 are separated by a diafragm 5, an electrolyte including iron chloride to be a positive electrode active substance is fed to the positive electrode, and an electrolyte including chromium chloride to be a negative electrode active substance is fed to the negative electrode, to exercise charge and discharge. And a specific amount 0.1 or more of sulfuric acid and/or nitric acid is included in the electrolyte of the battery. In a mixing solution system of HCl and H2SO4, for example, the density of Cl<-> ion is low while the density of H<+> ion is the same, and the soluble rate of iron chloride and chromium chloride which are active substances is improved, compared with a single solution system of HCl.
