ABSTRACT

Numerous studies have reported that good adhesion and fuorination of carbon materials in a fuoropolymer matrix enhance their electrical and mechanical properties. However, a composite reinforced with oxyfuorinated graphite has not been reported for improving mechanical properties. This paper discusses the fabrication of conductive fuorinated ethylene–pro�pylene (FEP)/oxyfuorinated graphite (f-graphite) composite bipolar plates (BPs) via compression molding. To investigate the efects of fuorinating graphite, graphite with a large particle size of 500 μm was mixed with FEP powder with a small particle size of 8 μm through ball milling. The FEP/graphite composites exhibited high anisotropic electrical conductivity with the in-plane conductivity much higher than the through-plane conductivity because of the planar orientation of the graphite sheets. Therefore, the mechanical properties of the composites such as fexural strength tended to deteriorate with increasing graphite content. In particular, the FEP/f-graphite composites exhibited excellent fexural strength of 12 MPa, much higher than that of FEP/graphite composites at 9 MPa with a graphite content of 80 wt%. The interfacial interaction between FEP and f-graphite led to improved physical compatibilization, which contributed to enhance the mechanical properties of these composites. Our results are a step toward developing BPs for use in high-temperature fuel cells and heat-sink components. Graphic abstract
