In a fuel cell system, it is possible to suppress fixation of a fluid drive device arranged in a fluid channel connected to a fuel cell body. The fuel cell system (10) includes a fuel cell stack (22), a system body (20) having respective elements for supplying a fuel gas and respective elements for supplying an oxidizing gas; and a control device (80). The control device (80) includes a fluid drive device drive processing unit (88) having a function to forcibly drive the fluid drive device for preventing fixation of the fluid drive device according to judgments made on a non-use time, an operation state of the system body (20), a film impedance state of the fuel cell, a temperature of the fuel cell stack (22), and a dark noise
L'invention porte sur un système de pile à combustible dans lequel il est possible de supprimer la fixation d'un dispositif d'entraînement de fluide placé dans un canal de fluide relié au corps de la pile à combustible. Ledit système (10) comporte: une pile de cellules (22); un corps (20) présentant des éléments d'alimentation en gaz combustible et en gaz oxydant; et un dispositif de commande (80). Le dispositif de commande (80) comprend: une unité de gestion (88) du fonctionnement du dispositif d'entraînement du fluide, l'activant en fonction d'évaluations: du temps de non utilisation; de l'état de fonctionnement du corps (20); de l'état d'impédance du film de la pile à combustible (20); de la température de la pile (22); et du bruit d'obscurité.
