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.

An Electrochemical Investigation of Potential Metallic

Although SS316L, SS347 and Ti had the better corrosion resistance, they still corroded and metal ions would migrate to membrane andn therefore degrade both the membrane and the fuel cell performance. Increasing attention is being paid to the use of metallic materials as a replacement for non-porous graphite in bipolar plates (BPs) for polymer exchange membrane (PEM) fuel cells.

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.

KONTIFLEX: Mass production of graphite bipolar plates

Bipolar plates are a major component of fuel cell stacks. They separate the reaction gases and cooling media from each other and distribute them to the corresponding fuel cell reaction area. Bipolar plates must have good electrical and thermal conductivity and be robust against chemical influences and high mechanical contact pressures in the cell.
