Abstract

The composite materials based on a thermosetting binder mark SFP and thermally expanded graphite and containing 50–70% of the filler are prepared by the method of hot pressing. It is studied how the physicochemical and mechanical characteristics of the composite depend on the method of filler introduction. The materials prepared by mixing air-dry components are shown to exhibit the high conductivity (up to 195 S/cm) and strength (above 25 mPa), the low interface contact resistance (less than 10 mΩ cm²), and the corrosion current not exceeding 1 µA/cm², which allows the high efficiency of energy conversion in SPFC to be reached.

用于燃料电池双极板的基于热膨胀石墨的复合材料

摘要通过热压法制备了基于热固性粘结剂标记 SFP 和热膨胀石墨的复合材料，其中含有 50-70% 的填料。研究了复合材料的物理化学和机械特性如何取决于引入填料的方法。结果表明，通过混合风干成分制备的材料具有高导电率（高达 195 S/cm）和强度（高于 25 mPa）、低界面接触电阻（小于 10 mΩ cm2）和不超过 1 µA/cm2 的腐蚀电流，从而实现了 SPFC 的高效能量转换。
