Cold starting is carried out by directly converting process gas into thermal energy by means of a catalytic reaction. The thermal energy is used to heat up the fuel cell stack, wherein the process of heating up the fuel cell stack is carried out separately from the operation of the fuel cell facility. To this end, heating elements (20, 40) form separate components in the fuel cell stack (10, 30), which are mounted in a predetermined order in said fuel cell stack (10, 30),
Selon l'invention, le démarrage à froid est provoqué par conversion direction du gaz de processus en énergie thermique au moyen d'une réaction catalytique et par utilisation de cette énergie thermique pour chauffer l'empilement de cellules électrochimiques. Le processus de chauffage de l'empilement s'effectue séparément du fonctionnement de l'installation à cellules électrochimiques. A cet effet, des éléments chauffants (20, 40) forment, dans l'empilement de cellules électrochimiques (10, 30), des composants séparés qui sont placés dans un ordre prédéterminé dans ce dernier.
