This utility model discloses a bipolar plate for a flow battery with a conductive metal sheet, comprising a front electrode plate, an intermediate substrate, and a rear electrode plate. The front electrode plate is a conductive plastic sheet, the intermediate substrate is a metal sheet, and the rear electrode plate is also a conductive plastic sheet. The intermediate substrate is composite-extruded between the front and rear electrode plates. By forming the front, intermediate, and rear electrode plates into a composite bipolar plate, the conductivity of the bipolar plate can be increased through the intermediate substrate. Simultaneously, using a metal sheet for the intermediate substrate effectively ensures the strength and toughness of the bipolar plate, preventing brittleness and leakage. Since the front and rear electrode plates are made of plastic, the weight is reduced. This material combination provides a bipolar plate with better conductivity, lower porosity, and lower cost. Furthermore, the composite extrusion method simplifies the manufacturing process and makes it easy to implement.
