PROBLEM TO BE SOLVED: To further increase charge and discharge capacities in an aqueous solution system.SOLUTION: A flow battery 10 includes: a case 12; a separator 18 for separating the inside of the case 12 into a positive electrode chamber 14 and a negative electrode chamber 16; a positive electrode collector 20 arranged in the positive electrode chamber 14; and a negative electrode collector 50 arranged in the negative electrode chamber 16. Also, a positive electrode side circulation path 32 is arranged between the positive electrode chamber 14 and a positive electrode reservoir container 30, and a positive electrode side circulation pump 38 is attached to the middle of the positive electrode side circulation path 32. Also, a negative electrode side circulation path 62 is arranged between the negative electrode chamber 16 and the negative electrode reservoir container 60, and a negative electrode side circulation pump 68 is attached to the middle of the negative electrode side circulation path 62. Then, positive electrode mediator contained electrolyte 22 is allowed to circulate by the negative electrode side circulation pump 38 so as to be brought into contact with the positive electrode collector 20, and negative electrode mediator contained electrolyte 52 is allowed to circulate by a negative electrode side circulation pump 68 so as to be brought into contact with the negative electrode collector 50, and charge and discharge is performed.SELECTED DRAWING: Figure 1 |
