h i g h l i g h t s < Development of ABSegraphiteeMWNT composite bipolar plates. < EIS successfully applies for understanding the corrosion mechanism of the composites. < MWNT concentration strongly affects the corrosion behavior of the ABSegraphite composites. < The best balance of properties was for the ABS-graphite composite with addition of 2 wt.% MWNT. a b s t r a c tComposite bipolar plates based on the proper mixing of multi-walled carbon nanotubes (MWNTs), synthetic graphite particles and acrylonitrileebutadieneestyrene (ABS) powder have been produced by hot compression molding. The corrosion properties of the molded plates were assessed through electrochemical impedance spectroscopy (EIS) and potentiodynamic polarization curves. Through-plane and in-plane electrical conductivities were determined. The relevance of electrochemical oxidation to the electrical conductivity of the composites was assessed by cyclic voltammetry. Thermal stability of the composites was examined by thermogravimetric analysis (TGA). The morphology of fractured surfaces of the plates was observed by scanning electron microscopy. The incorporation of MWNTs increased the inplane and through-plane electrical conductivity of the ABSegraphite composites. There was, though, a corresponding reduction of the corrosion resistance. The thermal behavior was little affected by the addition of MWNTs.

“…To develop some understanding, the total volume or surface of filler should be kept constant. The optimization of the conductivity may then be performed by adjusting the relative amounts of the different carbonaceous fillers [8,13,14,11,12]. A better filler compacity may thus be obtained, inducing an improvement of conducting paths between fillers allowing synergistic effect between fillers.…”

“…Even though the use of that kind of plastic reduces the production cost they have a low working temperature (70)(71)(72)(73)(74)(75)(76)(77)(78)(79)(80) C) and mechanical properties that limit the range of applications. Other thermoplastic used as matrix are polyphenylene sulfide (PPS), polyvinylidenefluoride (PVDF), polyarylene disulfide and liquid crystalline polymer (LCP) [130,132] which might increase the range of applications. TpC allows the use of injection molding process, a very well known industrial process, for channel fabrication.…”

Carbon materials are fundamental for the manufacturing of fuel cells. Several fuel cell components are made entirely of carbon in a graphitic form. In the present chapter, an overview of the different fuel cell carbon components and the materials used in their preparation will be presented. Novel approaches in the synthetic method, in order to impart desired properties, and in the manufacturing of the components will be shown. Also, relevant results on the latest research conducted will be discussed.
