Metal bipolar plates have advantages such as high strength, good conductivity and heat transfer, low energy loss and good sealing performance. Additionally, metal bipolar plates are easy to process with low processing costs, which can be manufactured with ultra-thin thickness with high volume-specific power characteristic. Metal materials have gradually become the first choice for bipolar plate materials. The design and manufacturing process of the flow channel structure are the key factors affecting the forming quality and working performance of metal bipolar plates. The traditional and new channel structures used in metal bipolar plates were compared, and the impact of structural changes on fuel cell performance was analyzed. Plastic forming technologies and equipment were summarized, such as stamping, hydroforming, rubber pad forming, roll forming, electromagnetic forming and special forming. Finally, the flow channel structure design and manufacturing process of metal bipolar plate are prospected.
