Filed:

Sep 14, 2007

Appl. No.:

11/855574

Inventors:

Charles Vesely - Andover MN, US
Bradford Palmer - Ham Lake MN, US
Xin Li - Blaine MN, US

Assignee:

Cummins Power Generation Inc. - Minneapolis MN

International Classification:

H01M 8/04

US Classification:

429 9, 429410

Abstract:

Methods and systems for maintaining near operational mode internal temperatures of a high temperature fuel cell system during a hibernation mode are provided. Embodiments of the claimed invention include powering an electric heater adjacent to the high temperature fuel cell system to heat the high temperature fuel cell system. The use of an electrical heater allows the fuel cell system to maintain approximate operation mode internal temperatures during a hibernation mode and eliminates the problems of excess noise, vibration and exhaust emissions typical of previous fuel cell system heating methods. Gross energy savings of 67% and a fuel consumption reduction rate of 33% have been shown when substituting this method with previous fuel cell system heating methods with no additional manufacturing costs.

H01M 8/04119

Abstract:

A system and method are provided for increasing efficiency of a solid oxide fuel cell (SOFC) system by recapturing water via a condensate extraction system that extracts water from a hot cathode exhaust flow of the SOFC stack. Further, the SOFC system can include a radiant heater which has a fuel inlet, an air intake, and an exhaust outlet independent and separate from the power generating components in the SOFC system. The radiant heater can bring the SOFC stack up to operating temperature quickly and/or maintain near operational mode temperatures of the SOFC stack during a hibernation mode.

Abstract:

A method of operating a multi-coil magnetic resonance imaging system, is disclosed which includes establishing initial circuit values of a drive circuit, loading a tissue model associated with a tissue to be imaged, loading target values for a variable of interest (VOI) associated with operation of two or more coils of a magnetic resonance imaging system, performing a simulation based on the established circuit values and the loaded tissue model, determining output values of the VOI based on the simulation, comparing the simulated output values of the VOI to the loaded target values of the VOI, if the simulated output values are outside of a predetermined envelope about the loaded target values of the VOI, then performing a first optimization until the simulated output values are within the predetermined envelope.
