The invention relates to a redox flow battery (1000) comprising n electrochemical cells 300 that are electrically connected in series (300), each cell including a cathode (310) and an anode (320) thatare separated by a membrane (330) and that are respectively passed through by a catholyte and an anolyte originating from a catholyte tank (110) and an anolyte tank (120). The cells are fluidically connected in parallel. A system for decreasing by-pass currents comprises: means (700) for injecting a gas into the inlet ducts (401) and outlet ducts (501) of the cathode and anode of (n-1) cells in order to form gas bubbles; and a device (800) for removing the gas bubbles, said device being placed, on the inlet ducts of the cathode and anode of the (n -1) cells, downstream of the means for injecting the gas and upstream of the cathode and anode of the cells. 本发明涉及氧化还原液流电池(1000)，其包含串联电连接的n个电化学单元300(300)，各单元包含阴极(310)和阳极(320)，所述阴极(310)和阳极(320)由间隔物(330)隔开且分别通过源自阴极电解质罐(110)和阳极电解质罐(120)的阴极电解质和阳极电解质。所述单元以并联方式流体连接。一种用于降低分路电流
