<p><P>PROBLEM TO BE SOLVED: To provide a redox flow cell (RF cell) capable of reducing a leakage amount of an electrolyte in a tank. <P>SOLUTION: An RF cell 1 charges and discharges by supplying a battery element 100c comprising a positive electrode, a negative electrode, and a diaphragm 101 with an electrolyte of tanks 106 and 107 via upstream pipes 11 and 21. Takeout ports of the electrolyte (openings 11t and 21t of the upstream pipes 11 and 21) are provided in the upper side of the tanks 106 and 107. The upstream pipes 11 and 21 are provided with low position parts 11L and 21L disposed in positions lower than the takeout ports. The tanks 106 and 107 house housing pipes 10B and 20B having leakage prevention holes 10h and 20h. The RF cell 1 is capable of reducing leakage of the electrolyte in the positive electrode tank 106 by a principle of a siphon via a reversed-u-shaped piping formed by a housing piping 10A and a part of the positive electrode upstream piping 11 at a time of an accident of the upstream piping 11 by having the small leakage prevention hole 10h disposed at the upper side of the tanks 106 and 107. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
