“…More recently, a large number of studies has been reported on metallic bipolar plates covered with various nitride films [84][85][86][100][101][102][103][104][105]. Tian [84] reported improvement in both corrosion resistance and interfacial contact resistance of CrN/Cr-coated 316L SS compared with bare 316L SS bipolar plates in simulated PEMFC environments.…”

“…The higher ICR of the bare 316L SS plates was attributed to the formation of a natural air-formed oxide film on the plate surface, resulting in lower conductivity. Cha et al [100] investigated the corrosion resistance and ICR properties of nitride films as protective layers for austenite 304 stainless steel bipolar plates. The plates were coated with NbN singlephase or NbN/NbCrN multiphase films using inductively coupled plasma-assisted D.C. magnetron sputtering system.…”

The proton exchange membrane fuel cell offers an exceptional potential for a clean, efficient, and reliable power source. The bipolar plate is a key component in this device, as it connects each cell electrically, supplies reactant gases to both anode and cathode, and removes reaction products from the cell. Bipolar plates have been fabricated primarily from high-density graphite, but in recent years, much attention has been paid to developing cost-effective and feasible alternative materials. Two different classes of materials have attracted attention: metals and composites. This paper offers a comprehensive review of the current research being carried out on metallic bipolar plates, covering materials and fabrication methods.

“…However the results are not at the desired level for PEMFC applications. A different solution was provided by Cha [11] who reported that a multiphase NbN/NbCrN film performed better than a single phased NbN film as a coating for metallic bipolar plates. The specimens were fabricated by sputtering Nb, Cr and using N 2 as reaction gas.…”

“…However, after a transient polarization test, the TiN coated sample achieved higher current density than the base SS substrate material [18]. Similarly, the NbN coating's corrosion resistance at high potential also needs to be improved [19]. Considering the embarrassing situation that it is hard to obtain high conductivity and great corrosion resistance at the same time, the idea of mixing Ti, Nb, TiN and NbN properly to combine the best of each of the advantages is proposed.…”

Corrosion Behavior and Conductivity of TiNb and TiNbN Coated Steel for Metallic Bipolar Plates

et al. 2019

To improve corrosion resistance and electronic conductivity of bipolar plates for proton exchange membrane fuel cell (PEMFC), coatings of TiNb and TiNbN on 316L stainless steel (SS) were prepared by magnetron sputtering. X-ray diffraction (XRD) measurements confirmed the existence of metallic nitrides in the TiNbN coating. Scanning electron microscope (SEM) tests showed that the deposited coatings provided smooth surfaces. Further electrochemical measurements indicated that the corrosion resistance of TiNb coating was significantly higher than that of substrate. At 0.19 V vs MSE, the long-term stabilized current density of TiNb/316L SS was lower than 1 μA·cm−2. The interfacial contact resistance (ICR) values between coating and carbon paper suggested that TiNb and TiNbN films had better contact conductivity than 316L SS substrate. In conclusion, TiNb coated 316L SS metallic bipolar plate material is a promising option for PEMFC.
