| 摘要 |
The present invention concerns an electrochemical system (100) including a stack of series connected electrochemical units (102). The system is controlled by a control circuit (104) and includes a plurality of differential amplifiers (114), each connected by two inputs to the terminals of an electrochemical unit, in order to supply a voltage representative of the potential difference present between the terminals of said electrochemical unit. Each representative voltage is sent to a control unit (106) arranged for converting said representative voltage into a numerical value transmitted to the control circuit. The system further includes, between each differential amplifier and the control unit, a buffer means (116) controlled by the control circuit. The buffer means is capable of saving the voltage representative of the potential difference present between the terminals of the electrochemical unit to which it is connected. The voltage is saved simultaneously by all of the buffer means.
