Carbon/carbon composite material, fuel cell bipolar plate, fuel cell and preparation method thereof
The invention provides a carbon/carbon composite material, a fuel cell bipolar plate, a fuel cell and a preparation method thereof, and the method comprises the following steps: dipping a continuous carbon fiber fabric in thermosetting resin, carrying out curing molding, carrying out carbonization treatment in an inert gas atmosphere, carrying out densification dipping, and carrying out carbonization treatment, so that the densified carbon/carbon composite material is obtained; and carrying out graphitization treatment on the densified carbon/carbon composite material in an inert gas atmosphere to obtain the final carbon/carbon composite material. The continuous carbon fibers are used as a reinforcing material, the thermosetting resin is used as an adhesive, and the process of curing, carbonization, densification impregnation, recarbonization and graphitization is adopted, so that the content of the carbon fibers in the composite material can be greatly increased, the high-strength and high-modulus mechanical properties of the carbon fibers are fully played, and the good electrical conductivity and thermal conductivity of the composite material are ensured. The composite material can be widely applied to the technical fields with requirements on electrical conductivity, thermal conductivity and mechanical properties.
本发明提供了一种碳/碳复合材料、燃料电池双极板、燃料电池及其制备方法，所述方法包括如下步骤：将连续的碳纤维织物浸渍于热固性树脂中，固化成型，然后在惰性气体气氛下进行碳化处理，再进行致密化浸渍，并进行碳化处理，得到致密化的碳/碳复合材料；将致密化的碳/碳复合材料在惰性气体气氛下进行石墨化处理，得到最终的碳/碳复合材料。本发明采用连续的碳纤维为增强材料，以热固性树脂为粘合剂，通过固化‑碳化‑致密化浸渍‑再碳化‑石墨化工艺，既可以大大提升复合材料中碳纤维的含量，充分发挥碳纤维高强高模的机械性能，又保证其具有很好的导电性和导热性。该复合材料可以广泛应用于对导电性、导热性以及机械性能均有要求的技术领域。
