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 (400-600C) 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 Altex' proven distillate fuel pre-reforming technology, which operates at or around 550C, with Evogy's proven low temperature SOFC technology, which also operates at or around 550C, to reliably convert JP-8 to power. By matching the prereforming and SOFC temperatures, the system design is simplified and the heat loss is minimized. Also by operating at 550C, the interconnect lifetime is improved, the system startup time is reduced, and the system thermal degradation is minimized, thus enhancing the system reliability and longevity. Under the Phase II effort, a 1kWe LTPR-SOFC will be designed and a prototype unit will be fabricated and tested on JP-8 in the laboratory, prior to delivery to the Army for independent testing.
