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.
