Patent number: 10265657Abstract: A vehicle exhaust system is provided and comprises a catalyst positioned in an exhaust passage of a vehicle. The catalyst is in the form of a washcoat supported on a substrate. The system includes a phase change material located adjacent to the catalyst to maintain the temperature of the catalyst between engine shut-down and subsequent start-up as well as to regulate the temperature during engine operation. In some embodiments, the phase change material comprises particles of a metal or metal alloy encapsulated in a ceramic material. The metal or metal alloy is adapted to have a phase change that occurs within a temperature range wherein the catalyst is active.Type: GrantFiled: February 14, 2017Date of Patent: April 23, 2019Assignee: Ford Global Technologies, LLCInventors: Kevin James Rhodes, Mark John Jagner, Andrew Robert Drews

Patent number: 9919294Abstract: Phosphorus tolerant or resistant three-way catalysts (TWC) are disclosed. The TWC may include a substrate defining a plurality of channels. It may include front and rear washcoat portions overlying the substrate and having respective first and second washcoat loadings, the first washcoat loading being at most 2.0 g/in3 and less than the second washcoat loading. The front washcoat portion may include a catalyst material supported on a support material comprising a cerium oxide, such as ceria or CZO, or a pre-phosphated material, such as AlPO4, or CePO4. In one embodiment, the support material may comprise at least 85 wt. % of a cerium oxide or at least 85 wt. % of a phosphate-containing material. The front portion and the underlying substrate may comprise from 3 to 25 vol. % of the three-way catalyst or the front portion may overly up to an initial 15% of an axial length of the substrate.Type: GrantFiled: April 27, 2016Date of Patent: March 20, 2018Assignee: Ford Global Technologies, LLCInventors: Paul M. Laing, Carolyn Parks Hubbard, Jeffrey Scott Hepburn, Eva Thanasiu, Giovanni Cavataio, Hungwen Jen, Mark John Jagner, Rachael Jean Harrington, Michael Daniel Shane

Patent number: 9468909Abstract: 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 ?A/cm2 Pt and may approach or achieve bulk Pt activity.Type: GrantFiled: June 27, 2014Date of Patent: October 18, 2016Assignee: Ford Global Technologies, LLCInventors: Jun Yang, Chunchuan Xu, Patrick Pietrasz, Kerrie Gath, Benjamin Pence, Mark John Jagner, James Waldecker, Shinichi Hirano, Michael Alan Tamor
