| titleOfInvention | Method for emergency driving of fuel cell system |
| abstract | The present invention relates to an emergency driving method for a fuel cell system, and to an emergency driving method for a fuel cell system capable of moving a vehicle to a safest place by driving the fuel cell system without generating a reverse voltage in a stack when a hydrogen pressure sensor fails. Its purpose is to provide In order to achieve the above object, a hydrogen pressure control valve for controlling the pressure of hydrogen supplied to the fuel cell stack, an inlet pressure sensor and an outlet pressure sensor installed in the hydrogen electrode inlet pipe and the hydrogen electrode outlet pipe of the fuel cell stack A method for emergency operation of a fuel cell system having a fuel cell system, the method comprising the steps of: checking whether an inlet pressure sensor and an outlet pressure sensor are faulty from a result of fault diagnosis of the inlet pressure sensor and the outlet pressure sensor; If both the inlet pressure sensor and the outlet pressure sensor fail, the emergency operation control mode is entered, and the control command value for controlling the opening degree of the hydrogen pressure control valve is set according to the current value required for the stack from a separate emergency operation control map. determining a control command value corresponding to a current stack demand current value; and controlling an opening amount of the hydrogen pressure regulating valve according to the determined control command value to supply hydrogen to the fuel cell stack at a pressure according to the opening amount so that emergency operation of the fuel cell system is performed. An emergency driving method is disclosed. |
