“…However, in the case of metallic bipolar plates, the use of appropriate joining techniques such as laser welding can significantly lower the inner contact resistance [139]. A summary of the above studies and several other works [92,[140][141][142][143][144] is presented in Table 3.…”

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.

“…But the commercial application is restricted, which is ascribed to the high cost and poor machining property of the material , . Stainless steel has been developed as bipolar plate of PEMFC because of the excellent electrical conductivity, prominent mechanical strength and popular price . However, the operating condition of PEMFC is so severe that stainless steel cannot remain stable, resulting in electrochemical corrosion and power loss in PEMFC stack .…”

The drawback of corrosion resistance and surface conductivity are two obvious defects to limit the large-scale application of 316L stainless steel (316L SS) as bipolar plate (BP) in proton exchange membrane fuel cell (PEMFC). A tantalum (Ta) modified coating was prepared by plasma surface modification technology on the surface of 316L SS bipolar plate to improve the functional performance. The electrochemical behavior of untreated 316L SS and Ta modified bipolar plate was investigated in simulated PEMFC operating environment. The results of potentiodynamic polarization, potentiostatic polarization and electrochemical impedance spectroscopy (EIS) reveal that the Ta coating considerably improves the corrosion resistance of 316L SS bipolar plate. The poten-tiodynamic polarization result shows that a more positive self-corrosion potential is obtained by Ta modified bipolar plate, and the corrosion current density is obviously reduced to 1.95 μA cm -2 and 0.14 μA cm -2 in simulated cathodic and anodic environment, respectively. The Ta modified bipolar plate exhibits a satisfactory interfacial contact resistance (ICR), and still remains lower ICR than bare substrate after potentiostatic polarization test for 4 h. In addition, the high water contact angle (94.5°) for Ta coated bipolar plate implies more superior hydrophobic performance, which is convenient for water management within the PEMFC.

“…For example, types 316L [3,6,7], 310S [4,8,[9][10][11][12][13] and 904L [5] stainless steels have been proposed as promising materials by Davies et al [4,5]: the cell performance improved with increasing chromium and nickel contents in the stainless steel. In general, addition of chromium and nickel is common to improve corrosion resistance of stainless steel.…”

“…To reduce the ICR at the similar level to graphite, however, surface modification is necessary for all stainless steels, except some kinds of special stainless steels containing boron-based [19,20] and carbon-based metal [21,22]. Since we have already developed an effective method to improve ICR between GDL and stainless steels [9,12], the problem of ICR for a bare ferritic stainless steel with GDL is not a critical issue. We, thus, focused on corrosion resistivity of ferritic stainless steels to find the optimum level of chromium content that meets the requirement under the PEMFC environment.…”

“…There are many works [3][4][5][6][7][8][9][10][11][12][13][14][15][16] that austenitic stainless steels [3][4][5][6][7][8][9][10][11][12][13] and Ni-based alloy [14][15][16] bipolar plates have preferable corrosion resistance in the real PEMFC environments. For example, types 316L [3,6,7], 310S [4,8,[9][10][11][12][13] and 904L [5] stainless steels have been proposed as promising materials by Davies et al [4,5]: the cell performance improved with increasing chromium and nickel contents in the stainless steel.…”

Ferritic stainless steels can be attractive bipolar plate materials of proton exchange membrane fuel cell (PEMFC), provided that the stainless steels show sufficient corrosion resistance, for instance, by eliminating interstitial elements such as carbon and nitrogen. In the present study, thus, ferritic stainless steels (19Cr2Mo and 22Cr2Mo) with extra low interstitials (ELI) are evaluated to determine demanded level of chromium content to apply them for PEMFC bipolar plates. In a simulated PEMFC stainless steel can be applicable to bipolar plates for PEMFC, especially 22 mass % of chromium content in ferritic stainless steel with ELI system is, at least, demanded to ensure stable cell performance.
