Abstract
Un bloc (3) de piles à combustible, monté en série avec d'autres blocs (3) de piles à combustible dans un dispositif d'alimentation en courant continu (1), et qui acquiert une résistance élevée en raison d'un défaut, fait obstacle à un flux de courant provenant des autres blocs (3). La puissance du dispositif d'alimentation en courant continu (1) s'en trouve réduite. Pour remédier à cet inconvénient, l'invention est caractérisée en ce qu'une diode de puissance (7) est montée en parallèle avec chaque bloc (3) de piles à combustible, grâce à quoi le courant provenant des autres blocs (3) circule sur le bloc (3) défectueux de piles à combustible.
