[0002] Fuel cells use hydrogen and oxygen in the air as raw materials, and generate electricity through chemical reactions under the action of catalysts. What is discharged is water, which does not cause air pollution. As one of the important components of fuel cells, bipolar plates have a significant impact on the cost and performance of batteries. At present, it is very difficult to manufacture bipolar plates with parallel flow channels with complex cross-sectional shapes, which require the use of specific molds and testing.

[0003] A mold for manufacturing fuel cell bipolar plates is disclosed in the Chinese utility model patent application announcement specification CN203817131 U.
