Abstract
An emergency starting system and an emergency starting method of a fuel cell hybrid vehicle perform an emergency start when a DC power converter for starting fails. The emergency starting system includes: a fuel cell and a super capacitor connected through a main bus terminal in parallel; a driving inverter connected to the main bus terminal; a driving motor connected to the driving inverter; a balance-of-plant configured to activate the fuel cell; a starting DC power converter configured to drive the balance-of-plant; and a starting controller configured to control the super capacitor at the time of a start. The starting controller includes a super capacitor relay, an initial charging relay, and an initial charging resistor, the initial charging relay includes a plurality of relays, and the initial charging resistor includes a plurality of resistors.
