摘　　要：针对目前机加工燃料电池石墨双极板、金属双极板的不足,研究了采用酚醛树脂(PF)、中间相碳微球(MCMB)、石墨和碳纤维(CF)为原料通过模压成型、渗碳烧结工艺制备复合材料双极板。结果表明,所研制的复合材料双极板具有更佳的综合性能,其制造成本低、效率高,碳元素含量达95%,压缩强度大于100MPa,弯曲强度大于30MPa,体积电阻率小于50×10-6Ω·m,所组装的单电池能满足燃料电池苛刻工作条件和性能上的要求。A phenol-formaldehyde resin（ PF）/mesocarbon microbead（ MCMB）/graphite/carbon fiber（CF） composite bipolar plate was developed by pressure forming and carburization sintering to overcome the defects of traditional graphite bipolar plate and metal bipolar plate in fuel cell. The results showed that this new bipolar plate had good combined properties, low cost and high efficiency with carbon content being 95 % ;its compressive strength was greater than 100 MPa, flexural strength was greater than 30 MPa, electrical resistivity was less than 50 × 10^6Ω· m,and it can meet the harsh working conditions and performance requirement of fuel cell.
