Publication number: 20240058743Abstract: Systems and methods are provided for integrating direct air capture of carbon dioxide with capture of carbon dioxide from a point source. The systems and methods can include exposing an adsorbent to a low CO2 content gas flow (e.g., air) at conditions similar to ambient conditions to perform an initial amount of sorption of CO2. The initial sorption results in a partially loaded sorbent having a first sorbent loading. The partially loaded sorbent can then be exposed to a flue gas and/or other gas flow that contains a higher CO2 content. This allows a second sorption step to be performed using a higher CO2 content gas, resulting in an additionally loaded sorbent having a second (higher) sorbent loading. The sorbed CO2 can then be desorbed from the sorbent.Type: ApplicationFiled: August 15, 2023Publication date: February 22, 2024Inventors: Kevin B. DALY, Rodrigo F. BLANCO GUTIERREZ, Justin A.

Patent number: 11742508Abstract: A reforming element for a molten carbonate fuel cell stack and corresponding methods are provided that can reduce or minimize temperature differences within the fuel cell stack when operating the fuel cell stack with enhanced CO2 utilization. The reforming element can include at least one surface with a reforming catalyst deposited on the surface. A difference between the minimum and maximum reforming catalyst density and/or activity on a first portion of the at least one surface can be 20% to 75%, with the highest catalyst densities and/or activities being in proximity to the side of the fuel cell stack corresponding to at least one of the anode inlet and the cathode inlet.Type: GrantFiled: November 26, 2019Date of Patent: August 29, 2023Assignees: EXXONMOBIL TECHNOLOGY AND ENGINEERING COMPANY, FUELCELL ENERGY, INC.Inventors: Everett J. O'Neal, Lu Han, Carla S. Pereira, Rodrigo F. Blanco Gutierrez, Timothy M. Healy, Carl A. Willman, Hossein Ghezel-Ayagh, Frank J. Dobek, Jr.

Patent number: 11695122Abstract: A layered cathode structure for a molten carbonate fuel cell is provided, along with methods of forming a layered cathode and operating a fuel cell including a layered cathode. The layered cathode can include at least a first cathode layer and a second cathode layer. The first cathode layer can correspond to a layer that is adjacent to the molten carbonate electrolyte during operation, while the second cathode layer can correspond to a layer that is adjacent to the cathode collector of the fuel cell. The first cathode layer can be formed by sintering a layer that includes a conventional precursor material for forming a cathode, such as nickel particles. The second cathode layer can be formed by sintering a layer that includes a mixture of particles of a conventional precursor material and 1.0 vol % to 30 vol % of particles of a lithium pore-forming compound.Type: GrantFiled: November 26, 2019Date of Patent: July 4, 2023Assignees: ExxonMobil Technology and Engineering Company, FUELCELL ENERGY, INC.Inventors: Abdelkader Hilmi, Gabor Kiss, Rodrigo F. Blanco Gutierrez, Timothy C. Geary, Ethan L. Demeter, Chao-Yi Yuh

Patent number: 11211621Abstract: Systems and methods are provided for operating molten carbonate fuel cells to allow for periodic regeneration of the fuel cells while performing elevated CO2 capture. In some aspects, periodic regeneration can be achieved by shifting the location within the fuel cells where the highest density of alternative ion transport is occurring. Such a shift can result in a new location having a highest density of alternative ion transport, while the previous location can primarily transport carbonate ions. Additionally or alternately, periodic regeneration can be performed by modifying the input flows to the fuel cell and/or relaxing the operating conditions of the fuel cell to reduce or minimize the amount of alternative ion transport.Type: GrantFiled: November 26, 2019Date of Patent: December 28, 2021Assignees: EXXONMOBIL RESEARCH AND ENGINEERING COMPANY, FUELCELL ENERGY, INC.Inventors: Timothy A.

Publication number: 20210159523Abstract: A fuel cell is provided including an anode configured to receive, and allow to pass through, an anode process gas, a cathode configured to receive, and allow to pass through, a cathode process gas, and an electrolyte matrix layer separating the anode and the cathode. One of the anode or the cathode has an extended edge seal chamber, and the fuel cell is configured to receive the anode process gas and the cathode process gas in substantially perpendicular directions relative to each other, and the extended edge seal chamber is configured to allow the anode process gas and the cathode process gas to pass through the anode and the cathode in substantially parallel flow paths.Type: ApplicationFiled: November 26, 2019Publication date: May 27, 2021Inventors: Keith E.
