ABSTRACT:
A system for monitoring a group of electrochemical cells (C1, . . . , Ci, . . . , Cn) arranged in series, wherein each cell (Ci) is provided for outputting a DC voltage (Vi) greater than a minimum value (Vmin). According to the invention, said monitoring system includes a corresponding set of n electronic components (D1, . . . , Di, . . . , Dn) arranged in series, wherein each component (Di) is biased by the DC voltage (Vi) of a corresponding cell (Ci) by means of a low-frequency connecting element (Li), and has a conductivity threshold voltage (Vs) no lower than said minimum value (Vmin); and a means (D) for measuring a high-frequency conductivity parameter of all of said components. The system is useful in fuel cells.
