PURPOSE: A current controlling method for the cold-starting of a hybrid vehicle is provided to reduce the amount of hydrogen required for cold-starting of the hybrid vehicle by preventing the degradation of a fuel cell stack. CONSTITUTION: A stack voltage is generated from a fuel cell and is in connection with resistance(S130, S140). A voltage command value is input to the high voltage side of a direct current-direct current converter. A high voltage battery is charged or discharged according to the voltage command value. The charging or the discharging of the high voltage battery is selectively implemented according to the entire voltage of a fuel cell stack and the set value of a minimum cell voltage. After the charging or the discharging, the starting of a hybrid vehicle is completed. |
