Abstract
A solid oxide fuel cell device is provided which prevents excessive rising of the temperature inside a fuel cell module during the startup process. In a startup process, control unit controls to cause a transition from a fuel gas reforming reaction process to a POX process, an ATR process, and a SR process, then to a generating process; when the cell stack temperature and reformer temperature in each process satisfy respectively set transition conditions, a transition to the next process takes place; if control unit determines a temperature rise assist state exists, it executes an excess temperature rise suppression control so that during at least the transition to the generating process, the reformer temperature does not exceed a predetermined value.
