Patent number: 10644331Abstract: A rapid start power unit and a method of operating a rapid start power unit are disclosed. A fuel cell converts combustible fuel into electrical power during a normal operational period after an initial start-up period when little to no electrical energy is produced. One combustion chamber receives unspent fuel emitted by the fuel cell and combusts the unspent fuel to generate a first heated gas stream. Another combustion chamber receives combustible fuel and burns the combustible fuel to generate a second heated gas stream during the initial start-up period. A turbine receives and is driven by the first and second heated gas streams to drive a drive shaft. A generator coupled to the drive shaft generates electrical power during the initial start-up period and supplemental power during the normal operational period. In an alternative embodiment, a two-stage combustion chamber is used instead of two serially-arranged separate combustion chambers.Type: GrantFiled: October 24, 2016Date of Patent: May 5, 2020Assignee: The Boeing CompanyInventors: Tina Stoia, Shailesh Atreya, Chellappa Balan, David Whelan, David J.

Patent number: 8231774Abstract: Apparatus, systems, and methods provide for the management of a high temperature electrolysis process. According to embodiments described herein, a fuel cell electrolyzer stack is utilized in an electrolysis process. One implementation includes the use of a solid oxide electrolyzer. Input voltage is cycled around a thermal neutral voltage such that the fuel cell electrolyzer stack cycles between operation in an exothermic mode and an endothermic mode. The waste heat generated by operation in the exothermic mode is used to support the endothermic operation. By cycling between operation modes, the temperature of the fuel cell electrolyzer stack may be controlled without the use of a cooling loop or recirculated reactant flow, and the efficiency of the electrolysis process is maximized.Type: GrantFiled: March 10, 2009Date of Patent: July 31, 2012Assignee: The Boeing CompanyInventors: Shailesh Atreya, Marianne E.

Publication number: 20120045699Abstract: Methods and systems provide for the creation of power, water, and heat utilizing a fuel cell. According to embodiments described herein, fuel is provided to a fuel cell for the creation of power and a fuel byproduct. The fuel byproduct is routed to a byproduct separation phase of a power and water generation system, where water is separated from the fuel byproduct. The remaining mixture is reacted in a burner phase of the system to create additional heat that may be converted to mechanical energy and/or utilized with other processes within the system or outside of the system. According to other aspects, the separated water may be utilized within a biofuel production subsystem for the creation of biofuel to be used by the fuel cell.Type: ApplicationFiled: August 20, 2010Publication date: February 23, 2012Inventors: Shailesh Atreya, David Whelan, Marianne E.
