    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.

    Abstract: In at least one embodiment, an oxygen reduction reaction catalyst (ORR) and a method for making the catalyst are provided. The method may include depositing a metal oxide on a graphitized carbon or graphene substrate. A platinum catalyst may then be deposited over the metal oxide to provide an ORR catalyst for use in, for example, a PEMFC. The metal oxide may be niobium oxide and may have an amorphous structure. The platinum catalyst may form a thin, electrically interconnected network structure overlaying the metal oxide. The ORR catalyst may be prepared by alternating the deposition of the metal oxide and the platinum catalyst, for example, using physical vapor deposition. The ORR catalyst may have a specific activity of at least 1,000 μA/cm2 Pt and may approach or achieve bulk Pt activity.

    Abstract: A method of forming a material for reversible hydrogen storage within a storage tank includes charging a mixture of a metal amide and a metal hydride to the storage tank, and chemically reacting the mixture at a reaction condition within the storage tank to form a thermally conducting composite material situated in the storage tank and for reversibly storing hydrogen. The composite material includes a three-dimensional and interconnected framework including a conductive metal. A method for reversibly storing hydrogen includes providing a storage tank and in situ chemically forming a composite material by charging a mixture of a metal amide and a metal hydride to the storage tank and chemically reacting the mixture at a reaction condition to form a thermally conducting composite material including a metal hydride and a substantially unreactive elemental metal framework. Hydrogen is absorbed into the composite material and is desorbed from the composite material.

    Abstract: In at least one embodiment, a method of scavenging hydrogen in a lithium-ion battery is provided. The method may comprise including an atomic intermetallic material in at least one of a positive electrode or a negative electrode of a lithium-ion battery and reacting hydrogen present inside the lithium-ion battery with the atomic intermetallic material to form a metal hydride. The method may include preparing a positive electrode slurry and a negative electrode slurry, each slurry including an active material and a binder, mixing an atomic intermetallic material including a proton absorbed state into at least one of the slurries, and casting the slurries to form a positive electrode and a negative electrode. The method may alternately include applying an atomic intermetallic material including a proton absorbed state to a surface of at least one of a lithium-ion battery positive electrode or negative electrode.
