    Abstract: Nitride stabilized metal nanoparticles and methods for their manufacture are disclosed. In one embodiment the metal nanoparticles have a continuous and nonporous noble metal shell with a nitride-stabilized non-noble metal core. The nitride-stabilized core provides a stabilizing effect under high oxidizing conditions suppressing the noble metal dissolution during potential cycling. The nitride stabilized nanoparticles may be fabricated by a process in which a core is coated with a shell layer that encapsulates the entire core. Introduction of nitrogen into the core by annealing produces metal nitride(s) that are less susceptible to dissolution during potential cycling under high oxidizing conditions.

  • Patent number: 8993472
    Abstract: Layered catalyst structures for fuel cells, particularly for a Proton Exchange Membrane Fuel Cell (PEMFC), are produced by a reactive spray deposition technology process. The catalyst layers so produced contain particles sized between 1 and 15 nm and clusters of such particles of a catalyst selected from the group consisting of platinum, platinum alloys with transition metals, mixtures thereof and non-noble metals. The catalyst layers without an electrically conducting supporting medium exhibit dendritic microstructure, providing high electrochemically active surface area and electron conductivity at ultra-low catalyst loading. The catalyst layers deposited on an electrically conducting medium, such as carbon, exhibit three-dimensional functional grading, which provides efficient utilization as a catalyst, high PEMFC performance at the low catalyst loading, and minimized limitations caused by reactant diffusion and activation. The catalytic layers may be produced by a single-run deposition method.

    Abstract: Disclosed is an electrode catalyst for a hydrocarbon-fueled solid oxide fuel cell. The electrode catalyst includes ceria supports and iridium-nickel alloy nanoparticles dispersed on the surfaces of the ceria supports. The electrode catalyst can be inhibited from carbon deposition, a general phenomenon in conventional hydrocarbon-fueled solid oxide fuel cells. Therefore, the catalytic activity of the electrode catalyst can be maintained even at high temperature for a long period of time. In addition, the electrode catalyst contains a minimum amount of a platinum group metal for inhibiting the occurrence of carbon deposition and has a maximized surface area. Therefore, the electrode catalyst exhibits improved catalytic activity and can be produced at greatly reduced cost while suppressing the occurrence of carbon deposition.
