To suppress a rapid voltage change in each power generation cell constituting a fuel cell stack, power storage devices (11) are respectively connected to each power generation cell (2) or each cell assembly including a plurality of power generation cells (2) of a fuel cell stack 1 to transfer electric charges between each power generation cell (2) and the corresponding power storage device (11). This allows a voltage control to be performed for each power generation cell (2), and thus improves the durability of the fuel cell stack.
Ce système permet de supprimer les variations de tension rapides se produisant dans chaque cellule productrice d'énergie composant une pile à combustible, par le raccordement de dispositifs (11) de stockage d'énergie correspondants à chaque cellule productrice d'énergie, ou à chaque bloc de cellules comprenant une pluralité de cellules (2) productrices d'énergie, d'une pile (1) à combustible, afin de transférer les charges électriques entre chaque cellule (2) productrice d'énergie et le dispositif (11) de stockage correspondant. Ce système permet de réguler la tension dans chaque cellule (2) productrice d'énergie et améliore ainsi la durabilité de la pile à combustible.
