“…of pitting corrosion initiation based on atomic force microscopy (AFM) observations of a nanoscale passive film on nickel [35]. Although there is no consensus, the passivity breakdown seems linked to local passive film defects (grain boundaries, vacancies), but also to the structure and the chemical composition of the passive film and those of the alloy underneath [30,36,37]. The structure and the chemical composition of passive films were analysed for austenitic stainless steels by auger emission spec troscopy (AES), X-ray photoelectron spectroscopy (XPS), time-of-flight secondary ion mass spectrometry (TOF-SIMS) or transmission electron microscopy (TEM) [38][39][40][41][42][43].…”

“…The surface layer can be enriched with chromium and nickel and depleted of iron at the same time. Iron oxides are more readily soluble, therefore they preferentially dissolve under anodic polarization, while the other components of the passive layer dissolve significantly more slowly, or not at all [86]. Thus, the corrosion resistance of stainless steels can be increased and the contact resistance reduced [49].…”

Metallic Material Selection and Prospective Surface Treatments for Proton Exchange Membrane Fuel Cell Bipolar Plates—A Review

The aim of this review is to summarize the possibilities of replacing graphite bipolar plates in fuel-cells. The review is mostly focused on metallic bipolar plates, which benefit from many properties required for fuel cells, viz. good mechanical properties, thermal and electrical conductivity, availability, and others. The main disadvantage of metals is that their corrosion resistance in the fuel-cell environment originates from the formation of a passive layer, which significantly increases interfacial contact resistance. Suitable coating systems prepared by a proper deposition method are eventually able to compensate for this disadvantage and make the replacement of graphite bipolar plates possible. This review compares coatings, materials, and deposition methods based on electrochemical measurements and contact resistance properties with respect to achieving appropriate parameters established by the DOE as objectives for 2020. An extraordinary number of studies have been performed, but only a minority of them provided promising results. One of these is the nanocrystalline β-Nb2N coating on AISI 430, prepared by the disproportionation reaction of Nb(IV) in molten salt, which satisfied the DOE 2020 objectives in terms of corrosion resistance and interfacial contact resistance. From other studies, TiN, CrN, NbC, TiC, or amorphous carbon-based coatings seem to be promising. This paper is novel in extracting important aspects for future studies and methods for testing the properties of metallic materials and factors affecting monitoring characteristics and parameters.

“…Some metals like stainless steel and titanium are general stable when they are used in fuel cells because they have low pH due to passivation for good corrosion characteristics. Stainless steel and titanium have strong mechanical strength and the gas permeation rate is low [188][189][190][191][192][193][194][195][196][197][198][199][200][201]. Several investigations have been conducted using stainless steel and titanium because even in acidic conditions, titanium and stainless steel still maintain their properties.…”
