A voltage monitor for monitoring the voltages of fuel cells (10) in a stack, is structured as a hierarchy of monitoring units. It comprises several slave monitoring units (60), each comprising a voltage- measuring circuit (60) and a plurality of voltage-measuring connections (5), each connection (5) being connected to one of the fuel cells, and the circuit (60) being arranged to generate a signal indicative of the voltage. A master monitoring unit (40) is arranged to receive the signals from all the slave monitoring units (50) and to monitor them for deviation from an acceptable range. |
