Abstract

In this study, the conductive polymer composite as bipolar plates for proton exchange membrane fuel cell (PEMFC) were developed by compression molding technique using Polypropylene (PP) as a polymer matrix and Graphite (G), Carbon Black (CB) and Carbon Nanotube (CNTs) as reinforcements. U.S. Department of Energy (US DOE) target values were taken as the benchmark for the development and investigation of thus conductive polymer composite. The effects of CNTs loading on the electrical and mechanical properties of G/CB/PP composite were investigated. By adding small amount of CNTs in to G/CB/PP composite thus will gives synergy effects on both electrical conductivity and mechanical properties. The small amount of CNTs such as I, 1.5, 2, 2.5 and 3 wt% will be added in to G/CB/PP composite. The conductive composite properties were characterized for electrical conductivity, flexural strength, density and shore hardness. The used of CNTs as a third filler of I up to 3 wt% in a G/CB/PP composite resulted in the in-plane electrical conductivity and flexural strength being 618.90 Siem and 58.08 MPa respectively. The density and shore hardness of G/CB/CNTs/PP composites are decreases with the increasing of CNTs weight percentage. However, the G/CB/CNTs/PP composite achieved the US DOE target for all the desire properties of bipolar plate.
