Abstract
Process for operating a high temperature fuel cell stack by the steps of: connecting the fuel cell stack in parallel to a power supply unit at a predefined temperature and/or voltage of the fuel cell stack, applying a voltage from the power supply unit of between 700 to 1500 mV per fuel cell across the fuel cell stack irrespective of the electro-motive force of the fuel cell stack, heating up the fuel cell stack from the predefined temperature to operation temperature while maintaining the voltage per fuel cell the power supply unit, maintaining the fuel cell stack at or above a predetermined operation temperature and/or above a predetermined voltage until the fuel cell stack is to be put into operation, supplying fuel to the fuel cell stack, and disconnecting the power supply unit followed by connecting a power-requiring load to the fuel cell stack.
