Flow cell frame with diversion structure, galvanic pile and processing method of galvanic pile

Abstract

The invention discloses a flow cell frame with a diversion structure, a galvanic pile and a processing method of the galvanic pile. The flow cell frame comprises a frame body (1), a frame inlet (2), a frame outlet (3), an inlet diversion channel (4) and an outlet diversion channel (5), wherein the frame inlet (2) and the inlet diversion channel (4) are arranged on the upper part of the frame body (1), the frame outlet (3) and the outlet diversion channel (5) are arranged on the lower part of the frame body (1), the middle part of the frame body (1) is provided with an active area (6), the active area (6) is respectively connected with the frame inlet (2) and the frame outlet (3) through the inlet diversion channel (4) and the outlet diversion channel (5), a diversion field (7) is arranged in the active area (6), and sealing lines (8) are arranged around the frame body (1). The invention can solve the problem of structural deformation in a cell and has the function of electrolyte diversion so as to uniformly distribute electrolyte and reduce the zinc dendrite generating probability, thereby improving the performance and the life of the cell. Additionally, the galvanic pile disclosed by the invention has the advantages of simplicity in installation and low failure rate.
