SOLID ELECTROLYTE FUEL CELL

The present invention comprises individual fuel cells 84 disposed within a fuel cell module 2; a reformer 20; a reformer temperature sensor 148 and generating chamber temperature sensor 142 for detecting the reforming state temperature inside the reformer, and a control section 110 for controlling the fuel cell module operation. In a state whereby a stopping of fuel cell module operation has been executed from a high temperature, this control section skips the normal startup ATR and executes a restart control by the SR when the reforming state temperature is within the normal startup ATR temperature band and a restart of operation has been executed.
