    Abstract: In at least one embodiment, a method of forming a platinum thin film is provided, including performing a first atomic layer deposition (ALD) process on a substrate using a first platinum organometallic precursor in a first step and an oxidizing precursor in a second step to form an at least partially coated substrate. A second ALD process is then performed on the at least partially coated substrate using a second platinum organometallic precursor in a first step and a reducing precursor in a second step to form a thin film of platinum on the substrate. The first ALD process may be performed for 5 to 150 cycles to nucleate platinum on the substrate surface and the second ALD process may be performed thereafter to grow the thin film and remove surface oxides. A conformal platinum thin film having a thickness of 1 to 10 monolayers may be deposited.

    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: 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.
