“…On the other hand, metal-based bipolar plates show significantly better electrical and mechanical properties compared to graphite-based bipolar plates [17]. But the primary challenge with metal-based bipolar plates is surface corrosion and dissolution in fuel cell environment which affects the overall performance of the PEM fuel cell [18,19]. There are several studies reported in literature to overcome the drawbacks of graphite and metal-based bipolar plates by development of polymer composite bipolar plates [20].…”

The most essential and costly component of polymer electrolyte membrane fuel cells is the bipolar plate. The production of suitable composite bipolar plates for polymer electrolyte membrane fuel cell with good mechanical properties and high electrical conductivity is scientifically and technically very challenging. This paper reports the development of composite bipolar plates using exfoliated graphite, carbon black, and graphite powder in resole-typed phenol formaldehyde. The exfoliated graphite with maximum exfoliated volume of 570 + 10 mL g -1 used in this study was prepared by microwave irradiation of chemically intercalated natural flake graphite in a few minutes. The composite plates were prepared by varying exfoliated graphite content from 10 to 35 wt.% in phenolic resin along with fixed weight percentage of carbon black (5 wt.%) and graphite powder (3 wt.%) by compression molding. The composite plates own desired mechanical properties with low bulk density, high electrical conductivity, and good thermal stability as per the U.S. department of energy targets at low filler concentration and can be used as bipolar plates for proton exchange membrane fuel cells.

“…The criterion to select SSs for BPPs applications sharply depends on the chemical composition of material as the nature and content of the alloying elements strongly influencing the composition of the passive film formed on the metal surface, which in turn affects its overall corrosion resistance [179]. Hornung and Kappelt [180] ranked different iron-based materials in accordance with the pitting resistance equivalent PRE = %Cr + 3.3ˆ%Mo + 30ˆ%N.…”

Fuel cells are the most clean and efficient power source for vehicles. In particular, proton exchange membrane fuel cells (PEMFCs) are the most promising candidate for automobile applications due to their rapid start-up and low-temperature operation. Through extensive global research efforts in the latest decade, the performance of PEMFCs, including energy efficiency, volumetric and mass power density, and low temperature startup ability, have achieved significant breakthroughs. In 2014, fuel cell powered vehicles were introduced into the market by several prominent vehicle companies. However, the low durability and high cost of PEMFC systems are still the main obstacles for large-scale industrialization of this technology. The key materials and components used in PEMFCs greatly affect their durability and cost. In this review, the technical progress of key materials and components for PEMFCs has been summarized and critically discussed, including topics such as the membrane, catalyst layer, gas diffusion layer, and bipolar plate. The development of high-durability processing technologies is also introduced. Finally, this review is concluded with personal perspectives on the future research directions of this area.

“…[2][3][4][5] To give a good adhesion to the gold coating on the surface of stainless steels, the passive film on the surface must be removed, and the passive film is usually removed before or during the gold coating process. 6) However, noble metals such as gold are so expensive that gold coating is hard to be practically adopted in terms of cost.…”

In order to produce 316L stainless steel separators with low contact resistivity and low cost, an attempt was made to reduce the contact resistivity of 316L steel by acid treatment. In the present work, the contact resistivity and corrosion resistance of acid-treated 316L stainless steels were investigated. Elemental composition, thickness and structure of the passive film on the steel surface were analyzed with transmission electron microscopy (TEM) and X-ray photoelectron spectroscopy (XPS). It is found that the contact resistivity of the stainless steel is closely related to the ratio of Fe in oxide-form in the passive film, irrespectively of the thickness of passive film. When the proportion of Fe in oxide-form to the sum of Fe and Cr in oxide-form, i.e. Feox/(Feox+Crox) is lower than ca. 40 at%, the contact resistivity is reduced to lower than 10 mΩ cm 2 . Besides, the corrosion resistance of the acid-treated stainless steel having low contact resistivity is very high. Power generation test shows that I -V characteristic and durability of the cell assembled using the acid-treated 316L steel separators of low contact resistivity are equivalent to those of the cell assembled using carbon-coated separators.
