PEM fuel cells have demonstrated their good energy efficiency and high power density per volume, but the high costs due to the noble metal catalysts, electrolyte membranes, and bipolar plates diminish the large scale marketing. Considering the potential of using graphene materials as low cost catalyst for the fuel cell applications, graphene nanocomposites were synthesized using a simple route by chemical oxidation and exfoliation of graphene oxide. The graphene nanocomposites obtaining was confirmed by characteristic analysis. Starting from graphite, the preparations of graphite oxide, graphene oxide, reduced graphene oxide and graphene based nanocomposites, as well as how to functionalize them with a compatible polymer, are described in this paper. The structure, morphology and properties were characterized during different preparation steps, using BET method, Scanning Electron Microscopy (SEM), Raman Spectroscopy, TGA analysis, XPS technique.
