Abstract
A solid oxide fuel cell (SOFC) system includes inner and outer enclosure walls each formed as an independent thermally conductive path. Each thermally conductive path comprises materials having a coefficient of thermal conductivity of greater than 100 W/m° K. The inner and outer enclosure walls are each thermally conductively coupled with an annular enclosure formed to enclose a fuel reformer module. The annular enclosure provides a fourth thermally conductive path disposed between the inner and outer enclosure walls having a coefficient of thermal conductivity of 50 W/m° K or less. A temperature sensor and thermal fuse are mounted to an outside surface of the outer enclosure. An active sensor and a passive fuse are provided to interrupt a flow of fuel into the fuel reformer when a temperature of the outer enclosure walls equal or exceed a failsafe operating temperature.
