摘要： Corrosion resistant, manganese-stabilized austenitic stainless steels with a low nickel content are used in bipolar plates, methods for fabricating the bipolar plates, and polymer electrolyte membrane (PEM) fuel cells comprising the bipolar plates. The bipolar plates are formed from high-manganese austenitic stainless steels comprising, in weight percents, 4.0 to 35 manganese, 0.5 to 1.5 nickel, 17 to 20 chromium, 0.2 to 0.5 nitrogen, up to 0.075 carbon, 0.5 to 1.0 silicon, up to 0.1 aluminum, 0 to 0.005 sulfur, and balance iron and incidental impurities. The steels exhibit suitable corrosion resistance, electrical contact resistance, and mechanical properties for high-corrosion applications such as use in bipolar plate materials for PEM fuel cells. The bipolar plates may comprise a solid plate of the steel, optionally coated with a highly electrically conductive material. Alternatively, the bipolar plates may comprise an economical substrate coated with the steel, optionally further coated with a highly electrically conductive material.

摘要： A flow field plate or bipolar plate for a fuel cell, where a surface of the flow field plate is textured or roughened to change the surface morphology of the plate. A conductive coating is deposited on the roughened surface where the roughness of the surface of the plate increases the hydrophilic nature of the coating. Therefore, if the coating is naturally hydrophobic, the surface roughness makes the coating hydrophilic to wick water away. If the coating is a conductive hydrophilic coating, then the surface roughness makes the coating super-hydrophilic, and may counter the effects of surface contamination that would act to make the hydrophilic coating less hydrophilic.
摘要翻译：用于燃料电池的流场板或双极板，其中流场板的表面被纹理化或粗糙化以改变板的表面形态。导电涂层沉积在粗糙表面上，其中板的表面的粗糙度增加了涂层的亲水性。因此，如果涂层是天然疏水性的，则表面粗糙度使得涂层具有亲水性以吸水。如果涂层是导电亲水涂层，则表面粗糙度使得涂层具有超亲水性，并且可以抵消表面污染的作用，从而使亲水涂层的亲水性降低。

摘要： The present invention provides an electrically conductive element for a proton exchange membrane fuel cell having low electrical contact resistance and high corrosion resistance. The conductive element comprises a corrosion susceptible metal substrate with a surface, which is preferably treated to activate the surface (i.e. to remove a passivation layer of oxides from the surface) with an acidic treatment solution. The treated surface is then overlaid with an electrically conductive, corrosion-resistant, protective coating to protect the substrate re-forming a passivation layer while exposed to the corrosive environment of the fuel cell. The present invention also provides methods of preparing an electrically conductive element to have low electrical contact resistance and high corrosion resistance.
