JP-8 Fueled Low Temperature Pre-Reformer and SOFC System (LTPR-SOFC) For Portable Applications

Low temperature Solid Oxide Fuel Cells (SOFC) operating on JP-8 and other distillate fuels are the ideal power sources for all applications, especially for portable power applications. By operating at lower temperature (400-600 C) these systems have faster response, quicker startup, better longevity, less heat loss, lower thermal signature, higher system efficiency and lower cost. Altex and Evogy have teamed up to develop the portable Low Temperature Pre-Reformer and SOFC (LTPR-SOFC) that can efficiently and reliably operate on JP-8 fuel. LTPR-SOFC combines the Altex's proven distillate fuel pre-reforming technology that operates at or around 550 C with Evogy's proven low temperature SOFC technology, which also operates at or around 550 C, to reliably convert JP-8 to power. By matching the prereforming and SOFC temperatures operation, the system design is simplified and the heat loss is minimized. Also by operating at 550 C, the interconnect lifetime in improved, the system startup time is reduced and the system thermal degradation is minimized, thus enhancing the system reliability and longevity. Under the Phase I, a 1 kWe LTPR-SOFC will be designed and a subscale unit will be fabricated and tested on JP-8. These activities will provide the basis for developing, fabricating, demonstrating and delivering a 1 kWe LTPR-SOFC to the Army under Phase II.
