As shown in FIG. 3, the power storage and supply system 20 of the present embodiment can utilize a voltage comparator 29 to determine whether the fuel cell 21 or the battery 26 should be powered. When the utility power is interrupted, the power source is first provided by the battery 26. At this time, since the voltage of the fuel cell 21 has not been established, the voltage comparator 29 is positive (+), and then passes through the second transistor switch control circuit 34. The second transistor switch 27 is turned on, and at this time, the first transistor switch 22 is still in the off state, so the online interactive uninterruptible power system 40 is completely supplied with the required power from the battery 26 for power storage and supply.
