Abstract
In this study, a polymer/graphite nanocomposite bipolar plate was prepared through bulk molding process. Nanoparticles of metal oxide such as zinc oxide (ZnO) and titanium dioxide (TiO2 ) were added to composite as secondary fillers. Epoxy resin was chosen because of its low cost and easy fabrication through bulk molding. In these nanocomposites, the percentage of resin was constant while graphite and nanoparticles were variable. The conductivity and mechanical properties of these composite were studied by standard test methods. The obtained results showed that the nanocomposites prepared with a high percentage of nanoparticles have the highest flexural strength. Scanning electron microscopy (SEM) showed that fillers disperse well in the matrix
