摘要
为确定MCMB/石墨复合材料双极板模压成型工艺参数,采用w(MCMB)∶w(石墨)=9∶1组成的复合材料制备一组试件并测试其性能.详细分析了不同模压成型压力和烧结温度等工艺参数对MCMB/石墨复合材料的电阻率、抗弯强度和抗压强度的影响,并简要分析了其形成的机理.结果表明:MCMB/石墨复合材料的电阻率和力学性能存在互斥性;MCMB/石墨复合材料双极板模压成型工艺的模压成型压力为3～4 MPa,烧结温度为900℃.
To gain the molding process parameters of MCMB/graphite composite bipolar plates,a group of samples being made up of w（MCMB）：w（graphite） = 9∶1 were prepared,and their performance was tested.Effects of different molding presses and sintering temperatures upon MCMB/graphite composite′s resistance rate,bending strength and compressive strength were analyzed respectively.The results show that mutually exclusive factors existed between resistance rate and mechanical properties of MCMB/Graphite composite.And the molding process parameters of MCMB/graphite composite bipolar plates were also obtained,of which molding press was 3~4 MPa and sintering temperature was 900 ℃.
