Emergency starting system and method for fuel cell hybrid vehicle

An emergency starting method of a fuel cell hybrid vehicle, comprising steps of:

• turning on ignition of a vehicle;
• determining whether a starting DC power converter of the vehicle fails;
• when the starting DC power converter fails, determining whether a remaining voltage of a super capacitor is equal to or greater than a reference voltage;
• when the remaining voltage of the super capacitor is equal to or greater than the reference voltage, performing an emergency start by using the super capacitor;
• wherein the fuel cell hybrid vehicle includes a super capacitor relay, an initial charging relay, and a resistor for charging the super capacitor at an initial start for starting of the vehicle;
• the initial charging relay includes a plurality of relays, and the initial charging resistor includes a plurality of resistors;
• and
• the step of performing of the emergency start comprises:
• activating a fuel cell by turning on at least one of the plurality of relays to drive a balance-of plant;
• when the fuel cell is activated, charging the super capacitor by turning on the plurality of relays;
• and
• when the charging of the super capacitor is completed, setting a driving preparation state by turning on the super capacitor relay.
