Abstract

La présente invention concerne un dispositif et un procédé pour démarrer et faire fonctionner une installation à piles à combustible (2) qui peut être reliée à un réseau à courant alternatif (10). Selon cette invention, on met en oeuvre un transformateur bidirectionnel (20) conçu de manière à transformer en courant alternatif, en fonctionnement normal, un courant continu produit par l'empilement de piles à combustible (4) de ladite installation à piles à combustible (2) pour alimenter le réseau à courant alternatif (10). Inversement, lors d'un processus de démarrage, un courant alternatif de l'installation à piles à combustible (2) fourni par le réseau à courant alternatif (10) est transformé pour l'alimentation dans un circuit intermédiaire à courant alternatif (14). Grâce à ces mesures, il n'est pas nécessaire de mettre en oeuvre des sources d'énergie supplémentaires et des appareillages complexes supplémentaires pour alimenter en énergie des consommateurs (6) de l'installation à piles à combustible (2), même lors d'un processus de démarrage.
