Electrolytic cell bipolar plate flow channel arrangement

Abstract

This utility model provides a bipolar plate flow channel device for an electrolytic cell, relating to the field of bipolar plates for electrolytic cells. The device includes a bipolar plate body and a flow channel assembly. The bipolar plate body comprises a plate and a flow channel body. The flow channel body is formed on the plate. The flow channel assembly is arranged within the flow channel body. The flow channel assembly includes a flow-enhancing groove and a flow-enhancing block. Multiple flow-enhancing grooves are evenly distributed on one side of the inner wall of the flow channel body. Multiple flow-enhancing blocks are evenly distributed on the other side of the inner wall of the flow channel body. The flow-enhancing groove has a V-shaped structure. The flow-enhancing block has an isosceles triangular structure, and the tip direction of the flow-enhancing block is the same as the tip direction of the flow-enhancing groove. This bipolar plate flow channel device has a simple and reasonable structure and ingenious design. By setting the flow-enhancing groove and flow-enhancing block in cooperation, it can not only optimize the flow path of the electrolyte and gas but also improve the mass transfer efficiency, thereby improving the effectiveness of this utility model.
