Abstract: A fuel cell electrode includes a carbon nanofiber substrate and a continuous film of up to 100 atom-thick monolayers forming a network of interconnected electrocatalyst nanoparticles deposited on the carbon nanofiber substrate such that at least some of the nanoparticles are directly adhered to uppermost nanofibers of the substrate to form a layer resistant to electrocatalyst depletion.

Abstract: A fuel cell oxidation reduction reaction catalyst comprising a carbon substrate, an amorphous metal oxide intermediate layer on the substrate, and an intertwined matrix of platinum and elemental niobium arranged to form a surface metal layer covering the intermediate layer such that upon oxidation, the niobium binds with oxygen resulting in strengthened bonds between the platinum and the intermediate layer.

Abstract: The present disclosure includes a fuel cell bipolar plate including a coating and methods for forming the coating. The bipolar plate may include a steel substrate and a coating contacting the steel substrate. The coating may include a plurality of alternating oxide-forming layers and elution resistant layers. The oxide-forming layers may include pure titanium, doped titanium, or a titanium alloy (e.g. doped/alloyed with niobium, zirconium, vanadium, silver, tantalum, yttrium, scandium, or nitrogen) and the elution resistant layers may include a noble metal or tantalum (e.g., gold, iridium, ruthenium, or tantalum). There may be 2-20 layers each of the oxide-forming layers and the elution resistant layers. The coating may prevent elution of iron ions from the steel substrate, for example, by forming oxide plugs in defects or pinholes in the oxide forming and/or elution resistant layers. The coating may also reduce the total usage of precious metals, such as gold.

Abstract: The present disclosure includes fuel cell bipolar plates and methods of forming a radical scavenging coating on a bipolar plate. The bipolar plates may include a steel substrate, a middle layer contacting the steel substrate and including a bulk material and a radical scavenging material, and a conductive layer contacting the middle layer. The radical scavenging material may include cerium, such as metallic cerium or a cerium oxide. The conductive layer may include a conductive carbon, such as a diamond-like carbon or coating (DLC). The radical scavenging material may comprise 0.1 wt % to 30 wt % of the middle layer. The middle layer may be deposited using PVD, and the radical scavenging material may be doped into the middle layer, for example, by co-sputtering it with the bulk material of the middle layer.
