	Abstract:To overcome some of the traditional material’s major disadvantages,a variety of composite bipolar plates have been developed. The compound structure bipolar plates consisting a metal core layer and a conductive polymer outer layer not only utilize the metal’s advantage , but also prevent the metal from being corroded. And the flow field can be easy obtained by injection moulding. The key problem of this kind bipolar plate is how to enhance the bond between two layers. The conductive polymer bipolar plate has the specific advantage, which is coated noble metal on, can increase the conductivity remarkably. The high polymer/ graphite composite bipolar plates are being improved in materials selection, formulation and preparation, the mechanical strength and the conductivity have been rised. The detail contents of some high conductivity bipolar plates are described in this paper.
