    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: 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: 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.
