Abstract: An operation mode control method for a fuel cell hybrid electric vehicle is provided to facilitate mode conversion by changing a control variable and each boundary value in an emergency fuel cell mode, an emergency electric vehicle mode, and an emergency LDC reset mode. A starting key is turned on and a power is applied to a BMS(Battery Management System)(S100). A connection state of an HDC and an LDC is confirmed(S101). Current and voltage boundary values are set and transmitted to the HDC and the LDC(S102). A high voltage battery line is connected by operating a battery connection relay to connect the battery and the HDC(S103). A control of buck and boost modes is performed by transmitting a voltage command to the HDC and LDC(S104). The high voltage is formed at a main bus terminal by the HDC and the voltage is formed at an MCU input terminal capacitor by operating an MCU connection relay(S105). A fuel cell is started by driving fuel cell components by a PDU(S106). If the start of the fuel cell is completed, the fuel cell and the main bus terminal are connected by operating the fuel cell connection relay and the driving of a hybrid mode is started(S107,S108).
