Abstract
A circuit connection control system of a fuel cell includes a point connection portion to which an anode current collecting portion and a cathode current collecting portion of each unit cell are electrically connected, a voltage measuring unit that measures an output voltage of each unit cell, a switching unit connecting the anode current collecting portions and the cathode current collecting portions of the plurality of unit cells at the point connection portion; and a DC-DC converter that converts a voltage generated from the fuel cell to a predetermined voltage. A method of operating the circuit connection control system includes measuring an output voltage of each unit cell; detecting a first unit cell showing an output voltage lower than a predetermined first voltage; and connecting the first unit cell in parallel to a second unit cell.
