摘　　要：以热塑性酚醛树脂(PF树脂)、天然鳞片石墨(NG)为主要原料,采用模压工艺制备NG/PF复合双极板,分别对比了不同粒度石墨,不同PF含量以及不同模压工艺对双极板性能的影响,得出最佳的制备条件为:325目鳞片石墨,10%(质量百分比)PF,模压温度为150℃,模压压力为70 MPa,模压时间为2 m in,以此条件制得的双极板完全满足聚合物膜燃料电池的要求。Thermoplastic phenol formaldehyde resin （PF） and natural crystalline flake graphite（NG） were chosen to make composite bipolar plate by compression molding. The influences of different graphite size, PF content, compression pressure, compression temperature and compression time on the properties of the NG/PF composite bipolar plates were investigated. The results show that the optimum graphite size is 325 mesh,PF content is 10%, compression pressure is 70 MPa, temperature is 150℃, time is 2 rain. Under these conditions the NG/PF composite plate can meet the need of PEMFC bipolar plate.
