This study addresses the weight and cost issues associated with polymer electrolyte membrane fuel cells (PEMFCs). The United States Department of Energy (DOE) has proposed specifications for bipolar plates to facilitate fuel cell commercialization. Our research explores the development of a polymer composite material using solution casting and recycled materials. The matrix consists of polystyrene, incorporating carbon black, graphite, and carbon nanotubes as fillers. Comparative analysis, presented in tabular form, demonstrates the superior performance of our composite material in terms of being lightweight and cost-effective when compared to existing composites. The suggested material exhibits favorable electrical conductivities, measuring 14.42 S/cm and 16.464 S/cm for in-plane and through-plane directions, respectively, along with a thermal conductivity of 0.38 W/m ^oC.
