Patent number: 9882223Abstract: A catalyst composition comprising at least one precious metal, wherein the catalyst composition is capable of catalyzing, in the presence of a halogen ion or a mixture of halogen ions, a charging reaction and a discharging reaction in a regenerative fuel cell. This disclosure relates to electrodes comprising those catalysts that are useful in fuel cells. The catalysts are active towards hydrogen evolution reaction (HER) and hydrogen oxidation reaction (HOR) and porous electrodes are made in a process designed to control their porosity. The catalysts and electrodes are employed in regenerative fuel cells comprising hydrogen and halogen acid or mixture of halogen acids. The catalysts are particularly useful in hydrogen/bromine reduction/oxidation reactions. The catalysts exhibit highly acceptable life and performance.Type: GrantFiled: January 24, 2011Date of Patent: January 30, 2018Assignee: RAMOT AT TEL-AVIV UNIVERSITY LTD.Inventors: Emanuel Peled, Arnon Blum, Adi Aharon, Nina Travitsky, Yaron Konra, Kobby Saadi, Vladimir Zel, Meital Goor, Meital Alon, Roy Gorenshtein

Patent number: 9627693Abstract: This disclosure relates to energy storage and generation systems, e.g., combination of flow battery and hydrogen fuel cell, that exhibit operational stability in harsh environments, e.g., both charging and discharging reactions in a regenerative fuel cell in the presence of a halogen ion or a mixture of halogen ions. This disclosure also relates to energy storage and generation systems that are capable of conducting both hydrogen evolution reactions (HERs) and hydrogen oxidation reactions (HORs) in the same system. This disclosure further relates to energy storage and generation systems having low cost, fast response time, and acceptable life and performance.Type: GrantFiled: January 24, 2011Date of Patent: April 18, 2017Assignee: RAMOT AT TEL-AVIV UNIVERSITY LTD.Inventors: Emanuel Peled, Arnon Blum, Adi Aharon, Nina Travitsky, Yaron Konra, Ido Tsamir, Vladimir Zel, Kobby Saadi, Meital Alon, Roy Gorenshtein

Patent number: 9012104Abstract: A bipolar plate and regenerative fuel cell stacks including the bipolar plates and membrane electrode assemblies (MEAs) alternately stacked. The bipolar plate comprises a plate main body formed of an electrically conductive material. The plate main body has a first surface and a second surface opposite the first surface. Each surface has reaction flow channels through which fluids pass. The reaction flow channels on the first surface have a plurality of ribs therebetween forming an interdigitate flow field pattern. The reaction flow channels on the second surface have a plurality of ribs therebetween forming an interdigitate flow field pattern or a flow field pattern different from an interdigitate flow field pattern, e.g., a serpentine flow field pattern.Type: GrantFiled: January 24, 2011Date of Patent: April 21, 2015Assignee: Ramot At Tel-Aviv University Ltd.Inventors: Emanuel Peled, Arnon Blum, Adi Aharon, Yaron Konra, Vladimir Zel, Kobby Saadi

Patent number: 8524071Abstract: The present invention provides a high capacity adsorbent for removing sulfur from hydrocarbon streams. The adsorbent comprises a composite material containing particles of a nickel phosphide complex NixP. The adsorbent is utilized in a sulfur removal process that does not require added hydrogen, and run at relatively low temperatures ranging from about 150° C. to about 400° C. The process of this invention enables “ultra-deep” desulfurization down to levels of about 1 ppm and less.Type: GrantFiled: April 19, 2010Date of Patent: September 3, 2013Assignee: ExxonMobil Research and Engineering CompanyInventors: Miron V. Landau, Mordechay Herskowitz, Iehudit Reizner, Yaron Konra, Himanshu Gupta, Rajeev Agnihotri, Paul J. Berlowitz, James E. Kegerreis
