Advanced Hybrid Thermoelectric-Solid Oxide Fuel Cell Energy Conversion for High Efficiency Portable Power
Agency / Branch:
DOD / OSD
Technology is rapidly advancing both in the area of thermoelectric (TE) modules and solid oxide fuel cells (SOFC). Advanced solid oxide fuel cells are theoretically capable of converting over 60% of the energy available in the fuel (based on the fuels lower heating value) to electricity at operating temperatures around 800 degrees C. The remaining 40% of the energy is converted to heat. With the development of high performance thermoelectric materials, it now appears that a significant portion of the waste heat produced by an SOFC system can be converted into useable electrical energy by thermoelectric devices. An integrated SOFC-TE hybrid, therefore, offers the potential of increased efficiency (lower fuel consumption) than a conventional SOFC. This project proposes a parametric investigation of the integration of the application of advanced SOFC and thermoelectric technologies to maximize the efficiency of a portable power generator with 250Watts of net output power. A laboratory test of a thermoelectric device heated by a solid oxide fuel cell is also discussed. A conceptual design of the integrated 250 Watt SOFC-TE power system will be created.
