Abstract：
 The structure of a collecting board for full-vanadium redox fluid cell comprises: the high-density graphite plate dipped by epoxy resin or phenol resin, and a S-shaped flow field with width rate of ridge and channel as 1:0.5~6 and the rate between the channel depth to channel width as 1:1~5. The advantages of this invention include: 1) small resistance, stable chemical property, and strong ability to bear large current charge/discharge; 2) strong rigidity and intensity; 3) smooth flow of the electrolyte, and little polarization on cell.
