Abstract: Bipolar plates play a crucial role in the performance and viability of proton exchange membrane fuel cells. Polymeric composites have demonstrated their potential as alternatives to graphite and metallic materials for bipolar plates due to their good corrosion resistance, lightweight nature, flexibility, and cost-effectiveness. However, these polymeric materials often suffer from low electrical conductivity. The incorporation of various electrically conducting fillers can improve the electrical conductivity of these materials. This work presents a comprehensive review of the utilization of polymeric materials-based composites for bipolar plates for proton exchange membrane fuel cells. Various aspects related to bipolar plates in proton exchange membrane fuel cells, including materials, fabrication techniques, applications, cost analysis, and the current status of proton exchange membrane fuel cells are discussed in this work. Both thermoplastic and thermoset-based composites are explored as matrix materials for bipolar plates, along with different conducting filler/reinforcement options, and their best results are also explored. The impact of traditional as well as emerging fabrication techniques on the performance of bipolar plates is evaluated, emphasizing the need to reduce the cost of bipolar plates for the commercialization of proton exchange membrane fuel cells. Furthermore, the paper also examines the applications and current status of proton exchange membrane fuel cells in India as well as worldwide.
