Corrosion study of SS430/Nb as bipolar plate materials for PEMFCs

Niobium-coated 430 stainless steel (SS430/Nb) specimens were evaluated as possible bipolar plate materials in conditions that resemble a typical PEMFC environment with respect to their interfacial contact resistance (ICR) and corrosion resistance. Results show that SS430/Nb demonstrated to have low...

Description
Summary:Niobium-coated 430 stainless steel (SS430/Nb) specimens were evaluated as possible bipolar plate materials in conditions that resemble a typical PEMFC environment with respect to their interfacial contact resistance (ICR) and corrosion resistance. Results show that SS430/Nb demonstrated to have low ICR values and very good corrosion resistance in comparison with commercial steel and Ni-based alloys. In addition, the ICR values are also comparable with those of graphite.
