Summary:There is a growing demand for polymeric composite materials, mainly, in industrial applications. For instance, bipolar plates for polymer electrolyte fuel cell in automobile applications. This kind of composite can replace with lower cost and greater efficiency metallic components. The basic requirement is that the composite must possess adequate electrical and mechanical properties for the particular application. The goal of the present paper is to analyze the effect of graphite powder and carbon Black weight percentages on the electrical properties of epoxy composite plates. Electrical conductivity tests were performed in different composites. This study shows that is possible to obtain a semiconductor behavior with both epoxy/graphite and epoxy/Carbon Black composites.
