Abstract: In one or more embodiments, an electrochemical device includes a substrate having a substrate surface; an amorphous metal oxide layer supported on the substrate surface; and a noble metal catalyst supported on the amorphous metal oxide layer to form a catalyst layer. The amorphous metal oxide layer may contact only 25 to 75 percent of the substrate surface. The amorphous metal oxide layer may include less than 10 weight percent of crystalline metal oxide. In certain instances, the amorphous metal oxide layer is substantially free of crystalline metal oxide.

Abstract: An oxygen reduction reaction catalyst (ORR) and a method for making the catalyst are provided. The method may include depositing (e.g., by PVD) conductive catalyst material onto a non-conductive substrate, such as particles or powder, to form an intermediate ORR catalyst. The intermediate ORR catalyst may then be heat treated and another deposition process may be performed to form a thin, electrically interconnected catalyst network layer overlying the non-conductive substrate. The catalyst material may include, for example, platinum, gold, or other platinum group or noble metals, or alloys thereof. The non-conductive substrate may be a ceramic, for example, yttria-stabilized zirconia (YSZ).

Abstract: A bipolar plate for a fuel cell includes an anode plate and a cathode plate. The anode plate has hydrogen flow channels on a first side of the anode plate and coolant channels on a second side of the anode plate. The cathode plate has a first side disposed against the second side of the anode plate to cover the coolant channels and has a second side defining a recessed pocket configured to receive a stream of air. A flow guide is disposed in the pocket such that an inlet manifold is formed along a first edge of the flow guide and an outlet manifold is formed along a second edge of the flow guide. The flow guide defines channels extending from the inlet manifold to the outlet manifold. A plurality of openings is defined by through the flow guide.

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.
