Redox flow battery

The invention relates to a redox flow battery. A battery module is internally provided with a battery unit or a stack and electrolyte tanks. The electrolyte is transported to the battery unit or the stack according to each application of each battery module, the pump position is replaced, and generation of shunt current can be epochly reduced. Besides, as each battery module is provided with theelectrolyte tank, the electrolyte transfer paths can be greatly reduced. In order to transfer the electrolyte, a pump is replaced by a pressure fluid control part for each module, the power needed by pump driving can thus be saved, and the battery efficiency can also be improved. 本发明涉及的氧化还原液流电池在电池模块内具备电池单元或堆叠体和电解液罐，按各电池模块的每一个应用用于向电池单元或堆叠体搬运电解液的代替泵的装置，从而能够划时代地减少分路电流的产生。此外，通过按每个电池模块具备电解液罐，从而能够飞跃性地减少电解液的移送路径，并且为了输送电解液，按每个模块具备利用了压力的流体控制部来代替具备泵，从而能够节省泵驱动所需的动力，并能够提高电池的效率。
