The composite bipolar plate of Docbond rand is produced by a series of processes such as impregnation, bending and seal of cold pressed unicellular plate The composite graphite base material. Microorganism lupine agent.waterway adhesive and gas path sealant used in the production process are independently developed and have a number of invention patents, with strong core competitiveness

The function of the bipolar plate is to provide a gas flow channel, prevent the hydrogen and oxygen in the battery gas chamber from colluding, and establish a current path between the cathode and anode in series. Under the premise of maintaining a certain mechanical strength and good gas barrier effect, the thickness of the bipolar plate should be as thin as possible to reduce the conduction resistance to current and heat
