Bipolar plate is a vital component of PEM fuel cells (PEMFCs), which supplies fuel and oxidant to reactive sites, removes reaction products, collects produced current and provides mechanical support for the cells in the stack. The design of the bipolar plates should minimize plate thickness for low volume and mass. The flow fields should provide for efficient heat and mass transport processes with reduced pressure drops. The weight, volume and cost of the fuel cell stack can be reduced significantly by improving layout configuration of flow field and use of lightweight materials. In this paper, four PEMFCs have been made to fabricate bipolar plates (BPPs) from substances graphite, stainless steel (SS316), aluminum and titanium. The present
results demonstrated that the PEMFC made by SS316 has more weight, stiffness and cell performance than other PEMFCs. Also, the PEMFC made by aluminum has the lowest expense. In addition, from the view of fabricating BPPs, SS316 BPPs are made easier than other BPPs
