Final Report Summary

Furthermore, the cell with the gold-coated plate is as good as the lowest cell built from graphite bipolar plates, while the cells build from pvd-coated plates are somewhat lower. From the single cell tests it can be seen that it is possible to reach almost a similar performance to that of graphite bipolar plates if stainless steel bipolar plates are used with a noble metal free coating.

This component of fuel cells provides mechanical support to the stack, circulates the gases that participate in the

A Review of Thermoplastic Composites for Bipolar Plate

2010/11/2Bipolar plates in the PEMFC have traditionally been made from graphite, since graphite has excellent chemical stability to survive the fuel cell environment. Other advantages of graphite are its excellent resistance to corrosion, low bulk resistivity, low specific density, and low electrical contact resistance with electrode backing materials.
