... of these contaminants on the corrosion resistance of the nitrided layer in polymer electrolyte membrane fuel cell (PEMFC) environments is not considered significant. The nitrided sample had a much higher contact resistance than the bare one and the contact resistance increased with the nitriding time. The high...

...R. F. Silva; A. Pozio Three different types of metallic bipolar plates (commercial stainless steels, Ni-based alloys, and nitride-coated steels) were investigated in terms of their interface contact resistance (ICR) and corrosion resistance in conditions typical of a proton exchange membrane fuel...

... and electrochemical corrosions in the PEM fuel cell operating environment. The major goals of this research are to find proper physical vapor deposition (PVD) coating materials which would enhance surface properties by making significant improvements on corrosion resistance and electrical conductivity at a reasonable...

... interdiffusion phenomena and transient formation of nodule iron–oxides. The dual ( FeAl ∕ Al ) coating exhibits the best corrosion resistance due to its higher Al surface content. Characteristics of the ESD coatings in terms of thickness, uniformity, and composition are also reported. 23 06 2004 29 07...
