The system (10) has a central control circuit (11) sending a selection signal to select one of electrochemical blocks of a fuel cell for measuring potential difference of the blocks of the fuel cell. A control module (12) realizes measurement of the potential difference of the blocks in response to the selection signal. The control module comprises differential amplifiers (26), where input of each amplifier is connected with terminals of the blocks so as to provide voltage representing the potential difference between the terminals of the blocks. |
