Definitions

  • the invention relates to a direct current supply device with a plurality of fuel cell blocks arranged in series.
  • a fuel cell block comprises a large number of fuel cells as well as devices for supplying and monitoring the fuel cells.
  • the fuel cells can be designed as a tubular or plates'.
  • the combination of hydrogen (H 2 ) and oxygen (0 2 ) in an electrochemical reaction generates electrical energy and heat, the hydrogen and oxygen combining to form water (H 2 0).
  • the fuel cells of a fuel cell block are electrically connected in series and generate direct current during operation.
  • the voltage that a fuel cell block can generate during operation depends on the number of its fuel cells. Arranging them in series, in other words connecting several fuel cell blocks in series, adds the voltage of the blocks, so that the DC power supply device achieves a high supply voltage in this way.
  • this fuel cell block is “electrically conductive”. With a number of fuel cell blocks connected in series, the electrical current generated in one fuel cell block thus flows through the other series-connected fuel cell blocks. In the event of a defect in a fuel cell block, which prevents the electrochemical reaction within the block, this block has one opposite

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.
