As a core component of the fuel cell, the bipolar plate plays key roles of electric conduction, heat conduction, cathode and anode gas isolation, electric stack structure support and the like. The material of the electrode plate is usually metal material, impermeable graphite, flexible graphite, etc. The metal material can be used for preparing ultrathin plates due to high strength and high gas barrier property, but the corrosion resistance is poor, so that the galvanic pile cannot have long service life when the bipolar plate is applied to the material. The impervious graphite has excellent corrosion resistance and strong electric and heat conduction capabilities, so that the problem of service life of the galvanic pile can be solved. However, the brittleness and complicated processing procedures of the material make it impossible to mass-produce, resulting in high cost. The flexible graphite material solves the problem of difficult processing of the material on the basis of having the advantages of impermeable graphite. The material is usually prepared into a light plate by a rolling mode, and then a unipolar plate with a flow field is prepared by a die pressing method. The continuous production can greatly reduce the processing cost of the material. Furthermore, the cost of the material itself is low.

However, the horizontal electrical conductivity and thermal conductivity of the flexible graphite plates produced by the prior art are much greater than the vertical electrical conductivity and thermal conductivity, which is contrary to the requirement of high vertical electrical conductivity and thermal conductivity of the plates. Chinese patent CN106876724A discloses a roll-in production method of flexible graphite unipolar plates for fuel cells, which can continuously produce flexible graphite unipolar plates, and improve production efficiency.
