Patent number: 10392567Abstract: An aspect of the present disclosure is a method that includes contacting an oxygenated compound and hydrogen (H2) with a solid catalyst, where the solid catalyst includes a metal carbide that includes a first transition metal, and the contacting converts at least a portion of the oxygenated compound to a deoxygenated compound. In some embodiments of the present disclosure, the metal carbide may include at least one of Mo2C and/or W2C.Type: GrantFiled: October 26, 2017Date of Patent: August 27, 2019Assignee: Alliance for Sustainable Energy, LLCInventors: Daniel Ruddy, Joshua A. Schaidle, Calvin Mukarakate, Abhijit Dutta, Frederick G. Baddour, Susan E. Habas

Patent number: 8367265Abstract: A solid oxide fuel cell includes an anode layer, an electrolyte layer over the anode layer, and a cathode layer over the electrolyte layer. At least one of the anode layer and the cathode layer defines a gas manifold. The gas manifold includes a gas inlet, defined by an edge of the anode layer or cathode layer, a gas outlet, defined by the same or a different edge of the anode layer or cathode layer, and a plurality of gas flow channels in fluid communication with the gas inlet and gas outlet. The gas flow channels can have diameters that conduct flow of gas from the gas inlet at substantially equal flow rates among the gas flow channels.Type: GrantFiled: December 15, 2009Date of Patent: February 5, 2013Assignee: Saint-Gobain Ceramics & Plastics, Inc.Inventors: James A. Salvatore, Vignesh Rajamani, Abhijit Dutta

Patent number: 8185214Abstract: A fuel cell system control system includes a fuel cell system and a controller. The controller includes a display and a processor configured to execute a program for managing an operation of a fuel cell state machine having a plurality of states and capable of executing logic to execute state transitions, and a fuel cell failure detection and correction program, configured to detect one or more fuel cell system failures and correct each detected failure while the fuel cell system continues to operate. The control process includes the steps of representing an operation of a fuel cell control system as a state machine having one or more states, controlling the operation of the fuel cell system using the state machine, executing one or more states of the state machine, and correcting operational errors in the fuel cell control system while the fuel cell system continues to operate.Type: GrantFiled: September 21, 2009Date of Patent: May 22, 2012Assignee: Bloom Energy CorporationInventors: Abhijit Dutta, Swaminathan Venkataraman
