The invention provides a redox flow cell stack which comprises at least two redox flow frames (7) and flow collecting bodies (3) with the number corresponding to that of the redox flow frames. The redox flow cell stack is characterized in that the redox flow frames are provided with a liquid inlet hole (71) and a liquid outlet hole (72) which are respectively used for leading electrolyte onto the surface of the flow collecting bodies and out of the surface thereof. The design of the invention can avoid the phenomena of seepage and weeping since the liquid inlet hole and the liquid outlet hole of the flow collecting bodies (3) are scoured by the electrolyte in the flowing process; meanwhile, the liquid inlet hole, the liquid outlet hole and flow channels can be conveniently designed on the redox flow frames, so that the liquid flow inside a cell can be more balanced and smooth.
