To reduce the costs of the bipolar plates of proton exchange membrane fuel cell （PEMFC） and improve the performance of PEMFC, the basic structure, working principle, main advantage and application areas of PEMFC were summarized. The features and functions of PEMFC＇ s bipolar plates were also analysed detailedly. The new materials and the new technologies of making PEMFC＇ s bipolar plates were introduced to reduce the production costs, such as the applications of mesocarbon microbeads （MCMB） and the gel-casting technology in the preparation of bipolar plates, and the catalytic graphitization technology for doped MCMB in the sintering process. The research provides the development direction of PEMFC and its bipolar plates.
