Abstract: A system and method of controlling an air blower for a fuel cell vehicle are provided. The method includes determining an operation amount of an air blower to secure a sufficient air flow rate under present operating conditions and obtaining information regarding clogging of an air channel or information regarding a back pressure using the operation amount of the air blower. In addition, a maximum operating range of the air blower is changed based on whether a present state is an air channel-clogged state or a back pressure-increased state.

Abstract: A method for controlling a startup of a fuel cell system is provided. The method includes comparing a voltage generated in a fuel cell stack when hydrogen is supplied to a fuel electrode of the fuel cell stack for a set period of time with a first reference voltage. A voltage of a unit cell of the fuel cell stack is compared with a second reference voltage for load connection when the voltage generated in the fuel cell stack is higher than the first reference voltage. A load is connected to the fuel cell stack when the voltage of the unit cell of the fuel cell stack is higher than the second reference voltage for load connection.

Abstract: A power net system of a fuel cell vehicle is provided. The power net system includes a fuel cell and a first switching unit that is configured to form and block an electrical connection between an output terminal of the fuel cell and a main bus. A load device diverges and is connected between the output terminal and the first switching unit. A reverse current blocking unit is disposed between the output terminal of the fuel cell and a node from which the load device diverges and is configured to block a current flow to the output terminal of the fuel cell. A second switching unit is configured to form and block an electrical connection between the output terminal of the fuel cell and the load device. A controller operates the first and second switching units to form the electrical connection between the main bus and the load device.
