Abstract: A monitoring system includes a plurality of monitoring devices adjacently provided to a group of integrated fuel cell stacks for measuring a voltage of the fuel cell units. Each of the monitoring devices includes a plurality of monitoring sensors adapted for electrically connecting to a predetermined set of fuel cell units and a MCU (Micro-Chip-Unit) for sequentially and circularly switching each two neighboring monitoring sensors for reading the voltage of each respective fuel cell. A CAN bus is provided for electrically and collectively interconnecting the monitoring devices with a central operator which is arranged in such a manner that when said the voltage of the respective fuel cell unit exceeds a safety range, the central operator generates an alert signal for indicating an abnormal operation of the respective fuel cell.

Abstract: A monitoring system includes a plurality of monitoring sensors for electrically connecting to fuel cell units of a fuel cell stack respectively, wherein a voltage of each of the fuel cell units is measured when two corresponding neighboring monitoring sensors are switched on. An alert controller includes a switch control sequentially switching each two neighboring monitoring sensors, and an alert device arranged when the voltage of the respective fuel cell unit is within a safety range, the switch control continuously switches on another two neighboring monitoring sensors until the voltage of the last fuel cell unit is read, and when the voltage of the respective fuel cell unit is out of the safety range, the alert device generates an alert signal for indicating an abnormal operation of the respective fuel cell unit of the fuel cell stack.
