Abstract: A method for synchronizing voltages of a fuel cell vehicle may synchronize the voltages of high voltage components in real time regardless of the completion of vehicle start-up in order to improve performance and control precision within a full range of operable voltages. The method includes a default voltage synchronization step in which, when the fuel cell vehicle starts, the voltages of the high voltage components are corrected based on an offset value, stored in advance in multiple auxiliary controllers for controlling the high voltage components, and the corrected voltages are further corrected according to a default voltage synchronization command of a main controller; and a real-time voltage synchronization step in which, after the default voltage synchronization step, the main controller transmits a target offset value to the auxiliary controllers, and the auxiliary controllers correct the voltages based on the target offset value.

Abstract: An emergency start device of a fuel cell vehicle having a motor as a driving source is provided and includes a fuel cell that supplies power to a motor and an air blower that supplies air to the fuel cell. A high voltage battery supplies power to the air blower and a direct current (DC) converter increases an output of the high voltage battery to transfer the output to the air blower. In addition, a first switch transfers or intercepts an output of the high voltage battery to the air blower. By directly transferring a voltage of the high voltage battery to the air blower, the fuel cell is driven, when the DC converter fails while driving by the high voltage battery.
