摘要： A redox flow battery (1) including: a battery cell (10) including a positive electrode (11), a negative electrode (12), and an ion exchange membrane (13); a positive electrode-side electrolyte tank (20); a negative electrode-side electrolyte tank (30); a positive electrode-side pipe connecting the battery cell (10) to the positive electrode-side electrolyte tank (20); and a negative electrode-side pipe connecting the battery cell (10) to the negative electrode-side electrolyte tank (30). The redox flow battery (1) performs charge and discharge by circulating respective electrolytes between the battery cell (10) and the positive electrode-side electrolyte tank (20) through the positive electrode-side pipe (21, 22) and between the battery cell (10) and the negative electrode-side electrolyte tank (30) through the negative electrode-side pipe (31, 32). A hydrogen oxidation catalyst (40) is provided adjacent to an inner surface of the negative electrode-side pipe (31, 32).

摘要： This battery body unit 10 for a redox flow battery performs charging and discharging by circulating an electrolyte in which active materials are dissolved to a battery cell 3 comprising electrodes 1 containing nanomaterials, an ion exchange membrane 2, and bipolar plates. The battery body unit 10 for the redox flow battery comprises an outer frame body 4, and the following which are installed inside the outer frame body 4: the battery cell 3; inner pipes (internal electrolyte going-way pipe 5, internal electrolyte returning-way pipe 6) that circulate the electrolyte to the battery cell 4; and electrolyte exchange members 7 forming a portion of the path of the inner pipes. The electrolyte exchange member 7 has a connection part 7a that connects to an external electrolyte going-way pipe 12 and a connection part 7b that connects to an external electrolyte returning-way pipe 13. The connection part 7b that connects to the external electrolyte returning-way pipe 13 is provided with a filter member 8 that does not allow nanomaterials to pass through, thus establishing a sealed system for the nanomaterials that prevents the nanomaterials from flowing out of the battery body unit 10.
