摘　　要：在不同工艺条件下将石墨蠕虫用压片机压制成柔性石墨板,测其电阻并计算电阻率,从而确定电阻率的影响因素。利用模压技术将柔性石墨板压制成燃料电池的流场板,装配燃烧电池,测其放电性能曲线并与其它材料流场板组装的燃料电池的放电性能曲线进行了比较。Flexible graphite plates were pressed from graphite worms by various processes.Influences on the resistances of the plates.measured by ac ohmmeter,were determined.The characteristic Ⅰ-Ⅴ curves of fuel cells with the flow fields pressed from the plates were compared with those from other materials.It was confirmed that this novel graphite plate was superior to others.
