Publication number: 20240072287Abstract: Molten carbonate fuel cell structures are provided that include a structural mesh support layer at the interface between the surface of the cathode and the cathode current collector. The structural mesh layer can have a mesh open area of 25% to 45%. In addition to providing structural support, the structural mesh layer can reduce or minimize ohmic resistance at the interface between the cathode and the cathode current collector.Type: ApplicationFiled: August 3, 2023Publication date: February 29, 2024Inventors: Abdelkader HILMI, Chao-Yi YUH, Timothy C.

Patent number: 11888199Abstract: An elevated target amount of electrolyte is used to initially fill a molten carbonate fuel cell that is operated under carbon capture conditions. The increased target electrolyte fill level can be achieved in part by adding additional electrolyte to the cathode collector prior to start of operation. The increased target electrolyte fill level can provide improved fuel cell performance and lifetime when operating a molten carbonate fuel cell at high current density with a low-CO2 content cathode input stream and/or when operating a molten carbonate fuel cell at high CO2 utilization.Type: GrantFiled: February 22, 2022Date of Patent: January 30, 2024Assignees: ExxonMobil Technology and Engineering Company, FUELCELL ENERGY, INC.Inventors: Jonathan Rosen, Heather A. Elsen, Gabor Kiss, William A. Lamberti, William C. Horn, Anding Zhang, Timothy C. Geary, Adam Franco, Abdelkader Hilmi

Publication number: 20230246215Abstract: Systems and methods are provided for improving the operation of molten carbonate fuel cells that include cathode current collector structures that have reduced contact area with the cathode in order to create increased cathode open surface area. Molten carbonate fuel cells that have cathode collectors with reduced contact area with the cathode can have an increased tendency to suffer structural difficulties during operation, such as formation of gaps between electrolyte and one or both electrodes. Use of a sintered anode in such a fuel cell can reduce or minimize the impact of such structural difficulties. The sintered anode can provide higher pore volume and/or a more stable pore structure and/or increased structural stability in a fuel cell that includes a cathode collector that has a reduced contact area with the cathode. This can maintain a more stable interface between the cathode and electrolyte and/or between the anode and the electrolyte.Type: ApplicationFiled: January 23, 2023Publication date: August 3, 2023Inventors: Jonathan S. ROSEN, Gabor KISS, Timothy A. BARCKHOLTZ, Lu HAN, William A. LAMBERTI, William C. HORN, Abdelkader HILMI, Timothy C. GEARY, Carl A. WILLMAN, Adam W. FRANCO

Patent number: 9128076Abstract: The present techniques are directed to a method for microprobe analyses of isotope ratios in inhomogeneous matrices. The method includes selecting matrix standards that have matrices that resemble a target matrix. A bulk isotope analysis is run on each of the matrix standards to determine a bulk isotope ratio value. A microprobe analysis is run on each of the matrix standards to determine a microprobe isotope ratio values for each of the plurality of matrix standards. Spurious values are eliminated from the microprobe isotope ratio values. The microprobe isotope ratio values are averaged for each of the matrix standards to create an average microprobe isotope ratio value associated with each of the matrix standards. The bulk isotope ratio value for each of matrix standards is plotted against the average microprobe isotope ratio value associated with each of the matrix standards to create a matrix corrected calibration curve.Type: GrantFiled: January 6, 2011Date of Patent: September 8, 2015Assignee: ExxonMobil Upstream Research CompanyInventors: William A.
