Abstract
The present invention provides a system and method for starting a fuel cell vehicle in an emergency, which can start the fuel cell by supplying necessary air to the fuel cell even in the event of a failure or malfunction of a high voltage system, the high voltage system including a high voltage DC-DC converter and a high voltage battery which are generally used as a power source of an air blower during start-up of the fuel cell. In particular, the present invention provides a system and method for starting a fuel cell vehicle in an emergency, in which a controller drives an air blower by a voltage output from a low voltage battery to start the fuel cell in an emergency, if it is determined that there is a failure or malfunction in the high voltage system during start-up of a fuel cell system.
