An emergency power supply system using a fuel cell includes a low voltage DC converter (LDC) which converts the output voltage of bidirectional high voltage converter or the output voltage of fuel cell stack into a low voltage and supplies the converted voltage to a low voltage battery; a DC/DC converter which converts the output voltage of the fuel cell stack or the output voltage of the bidirectional high voltage converter into a low voltage; and a fuel cell controller which determines whether the output voltage of the DC/DC converter is to be supplied to the output voltage supply line of the low voltage battery. |
