摘　　要：综述了用于质子交换膜燃料电池的模压膨胀石墨/树脂复合双极板的树脂选型以及膨胀石墨:树脂的配比对双极板性能的影响,所选树脂除了要能保证双极板的较高机械强度和气密性外,还要有利于低成本化的模压生产,才能有效地促进燃料电池的发展,推动其商业化。为了弥补双极板加入树脂后带来的电导率下降的问题,还需加入碳纤维、碳纳米管等辅助导电填料。此外,模压工艺及参数的选择与确定对双极板的性能也有直接影响。The resin and expanded graphite used to prepare the mould pressing composite bipolar plates of fuel cells were discussed： the influence of ratio of resin on bipolar plates, the resin would not only ensure the high mechanical strength and gas permeability of bipolar plates, but also would be beneficial to reduce the manufacture. It could help to develop the fuel cells and marketization. In order to make up the decline of electrical conductivity when adding resin to bipolar plates, some auxiliary conductive filler should be added, such as carbon fiber, carbon nano tube to bipolar plates. Furthermore, the technological parameter of mould pressing would influence on the property of bipolar plates.
