Abstract: A system and method for controlling a fuel cell of a vehicle are provided. The method includes sensing a time point when pressure control is necessary by sensing whether an output of the fuel cell is additionally necessary or whether the fuel cell can be in a dry-out state. In response to sensing that the pressure control is necessary, a required valve opening degree of an air outlet is derived by substituting a target air pressure for a data map. A fuel cell air outlet valve is then adjusted based the derived valve opening degree of the air outlet.

Abstract: A method and system for controlling a voltage in a stop-mode of a fuel cell vehicle are provided. The method includes detecting whether a fuel cell enters the stop-mode and calculating a voltage command value of a bus terminal based on available charging power of a battery representing a level of power chargeable in a high voltage battery when the fuel cell enters the stop-mode. A converter connected between the high voltage battery and the bus terminal is operated to adjust the voltage of the bus terminal to be the voltage command value of the bus terminal. Additionally, power consumption of an electric field load of a vehicle is increased when the voltage is adjusted and then the voltage of the fuel cell measured by a voltage sensor is equal to or greater than a reference voltage preset in a memory.

Abstract: A driving control method and system of a fuel cell system are provided. The method includes determining, by a controller, a dry state of a fuel cell stack and stopping an air blower, which supplies air to the fuel cell stack, using different processes based on whether the fuel cell stack is in the dry state. Accordingly, the time for which an open circuit voltage (OCV) is maintained is reduced and durability of the fuel cell is improved by preventing dry-out of the fuel cell stack.
