Abstract: PURPOSE: An emergency driving method for fuel cell vehicle is provided to enhance control logic without system change or hardware addition, thereby configuring additional emergency driving modes. CONSTITUTION: A vehicle controller and air supply controller checks communication state with each other. When the air supply controller checks a communication disconnection state for a fixed time, the air supply controller controls a driving operation of an air supply device for supplying air to a fuel cell stack with a self-determined air flux. The vehicle controller determines an abnormal state of a fixed air flux by receiving an input of air flux detection value supplied to the fuel cell stack from an air flux sensor. The vehicle controller drives the vehicle in an emergency driving mode by operating an operating motor with a fuel cell stack output.
