Operation control device and method for fuel cell vehicle
An operation control device for a fuel cell vehicle includes: a stack current determination unit monitoring a stack current of the fuel cell stack and determining whether an operation state of a fuel cell stack is in an upper-limit voltage limiting section; a battery state determination unit monitoring a state of charge (SOC) of a high voltage battery and determining whether the SOC of the high voltage battery is in a set reference SOC range; and an air flow rate control unit determining a compensation for an air flow rate of an air supply system according to the SOC of the high voltage battery, and outputting a control signal to an air compressor and an air pressure control valve according to the compensated air flow rate, when the operation state of the fuel cell stack is in the upper-limit voltage limiting section.
