Abstract

A voltage monitoring system (20) includes: switch circuits (31 to 35) that are provided one by one for fuel cells (FCl to FC5) and that are connected to both anodes and cathodes of the fuel cells (FCl to FC5); a transformer (50) that sequentially switches the connected states of the switch circuits (31 to 35) to sequentially input the respective voltages of the fuel cells (FCl to FC5) as input voltages; and a maximum/minimum value detecting circuit (60) that uses the output voltages of the transformer (50) to detect a maximum voltage and/or minimum voltage of the fuel cells (FCl to FC5).
