A fuel cell power management system is provided to improve the marketability of a fuel battery and to maintain a fuel battery in a good condition by measuring and managing the state of the fuel battery by controlling temperature, voltage, and current by operating a cooling fan or pump to the determined specification value. A fuel cell power management system includes a sub battery(1), a DC/DC converter(9), a first switch(7), a battery charger, a DC/DC converter(3), a second switch(6), a voltage and current measurement sensor(14), a measurment circuit unit(8), and a microprocessor(10).
