摘　　要：研究了采用中间相碳微球（MCMB）／石墨复合材料，通过常温模压成型、1000℃埋碳碳化烧结工艺制备双极板：研究了不同MCMB加入量对压缩强度、弯曲强度和电阻率的影响，结果表明有更佳的综合性能，其制造成本低、效率高，抗压强度〉152MPa，抗弯强度〉40MPa，电阻率〈30μΩ·m，满足燃料电池苛刻工作条件和性能上的要求。Bipolar plates in Proton Exchange Membrane Fuel Cell （PEMFC）, which influence not only the performance but also the cost of the stack, have been the obstacle for the industrialization of PEMFC. The traditional materials of bipolar plates and its processes are reviewed. Specially, the materials and the advanced processes for bipolar plates are discussed. Focusing on the effect of the composite materials, MCMB/graphite composite materials bipolar plate are produced. It has low cost and hlgh-power, compressive strength 〉 152 MPa, flexural strength 〉40 MPa, electrical resistivity 〈30μΩ·m. It can meet the demand of fuel cell.
