The present invention concerns an electrochemical system () including a stack of series connected electrochemical units (). The system is controlled by a control circuit () and includes a plurality of differential amplifiers (), 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 () 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 () 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.

Each control module includes a mechanism to communicate with the control circuit, so that the control circuit can control the shunt circuits belonging to different control modules.

Shunt system for cells in a fuel cell stack

The invention concerns a driving system for a hybrid-powered motor vehicle. It includes a generator set producing a direct current used by a driving set with an electric motor for driving at least one driving wheel of the vehicle. Using an accelerator, the driver gives a power set-point signal that is used by a first adjusting device which acts on the thermal engine, the generator, and the AC/DC converter of the generator set. A second adjusting device adjusts the power of the driving set as a slave of the generator set, according to the variations in the voltage of the supply circuit with respect to a desired voltage, without considering the signal from the accelerator.
