Patent number: 7951500Abstract: In one embodiment the present invention provides for an anode side gas flow heater for a fuel cell generator that comprises a recirculating anode gas flow 28, at least one burner 24, and an energy source 22. The energy source heats the burner, the anode gas flow passes over the at least one burner and is heated, and the heated anode gas flow is then passed through the anode side of the fuel cell generator 4, where the fuel cell generator is heated.Type: GrantFiled: May 25, 2006Date of Patent: May 31, 2011Assignee: Siemens Energy, Inc.Inventors: Stephen E. Veyo, Raymond A. George

Patent number: 7056611Abstract: A method and system are provided for improved control of the operating temperature of a fuel cell (32) utilizing an improved temperature control system (30) that varies the flow rate of inlet air entering the fuel cell (32) in response to changes in the operating temperature of the fuel cell (32). Consistent with the invention an improved temperature control system (30) is provided that includes a controller (37) that receives an indication of the temperature of the inlet air from a temperature sensor (39) and varies the heat output by at least one heat source (34, 36) to maintain the temperature of the inlet air at a set-point Tinset. The controller (37) also receives an indication of the operating temperature of the fuel cell (32) and varies the flow output by an adjustable air mover (33), within a predetermined range around a set-point Fset, in order to maintain the operating temperature of the fuel cell (32) at a set-point Topset.Type: GrantFiled: July 16, 2002Date of Patent: June 6, 2006Assignee: Siemens Power Generation, Inc.Inventors: Thomas R. Fabis, Joseph M. Makiel, Stephen E. Veyo

Patent number: 6610434Abstract: A fuel cell generator contains a plurality of fuel cells (6) in a generator chamber (1) and also contains a depleted fuel reactor or a fuel depletion chamber (2) where oxidant (24,25) and fuel (81) is fed to the generator chamber (1) and the depleted fuel reactor chamber (2), where both fuel and oxidant react, and where all oxidant and fuel passages are separate and do not communicate with each other, so that fuel and oxidant in whatever form do not mix and where a depleted fuel exit (23) is provided for exiting a product gas (19) which consists essentially of carbon dioxide and water for further treatment so that carbon dioxide can be separated and is not vented to the atmosphere.Type: GrantFiled: August 10, 2000Date of Patent: August 26, 2003Assignee: Siemens Westinghouse Power CorporationInventors: Robert Draper, Stephen E. Veyo, Richard E. Kothmann

Patent number: 6492048Abstract: A fuel cell generator contains a plurality of fuel cells (11) in a generator chamber (20), where oxidant (13) and fuel (1) are fed to the generator chamber (20), where both fuel and oxidant react to form depleted fuel and depleted oxidant, which are separated by steam (2) at a pressure higher than that of both the depleted oxidant stream and the depleted fuel stream, and where all oxidant and fuel passages do not communicate with each other, so that fuel and oxidant (in whatever form) do not mix, and where depleted fuel (26), consisting essentially of carbon dioxide and water, exits for further treatment, so that the remaining carbon dioxide can be separated from the remaining water and is not vented to the atmosphere.Type: GrantFiled: August 10, 2000Date of Patent: December 10, 2002Assignee: Siemens Westinghouse Power CorporationInventors: Robert Draper, Stephen E. Veyo
