Title
(EN) WATER TANK HEATING METHOD AND UNIT, ELECTRONIC DEVICE AND SOFC SYSTEM
(FR) PROCÉDÉ ET UNITÉ DE CHAUFFAGE DE RÉSERVOIR D'EAU, DISPOSITIF ÉLECTRONIQUE ET SYSTÈME SOFC
Abstract
(EN) The invention provides a water tank heating method and unit, an electronic device and a solid oxide fuel cell (SOFC) system. Before the SOFC system is started, ice in a water tank has been heated up, so after the SOFC system is started, the heating time of the heated ice, i.e., the thawing time of the water tank, will be shortened. Further, in the ice heating process, a pre-set needed SOFC thawing time determined according to current stack outlet temperature is used as a heating control parameter. As the stack outlet temperature is a key factor influencing the starting time of the SOFC system, the heating control will be more accurate if the pre-set needed SOFC thawing time corresponding to the stack outlet temperature is used as a heating control parameter.
(FR) L'invention concerne un procédé et une unité de chauffage de réservoir d'eau, un dispositif électronique et un système de pile à combustible à oxyde solide (SOFC). Avant le démarrage du système SOFC, de la glace dans un réservoir d'eau a été chauffée, de telle sorte qu'après le démarrage du système SOFC, le temps de chauffage de la glace chauffée, c'est-à-dire le temps de décongélation du réservoir d'eau, sera raccourci. En outre, dans le processus de chauffage de glace, un temps de décongélation de SOFC requis prédéfini, déterminé selon la température de sortie de pile actuelle, est utilisé comme paramètre de commande de chauffage. Comme la température de sortie de pile est un facteur clé influençant le temps de démarrage du système SOFC, la commande de chauffage sera plus précise si le temps de décongélation de SOFC requis prédéfini correspondant à la température de sortie de pile est utilisé comme paramètre de commande de chauffage.
