Abstract

An apparatus and method for diagnosing failure of an air supply system of a fuel cell system are provided to accurately and promptly sense various fault states of an air supply system and provide such fault sensing information to a driver in advance to allow the driver to recognize the necessity of fixing the system, thus enhancing driving safety. The apparatus for diagnosing failure of an air supply system of a fuel cell system includes a flow rate sensor installed in an air supply line and configured to measure an air flow rate, a power sensor configured to measure power consumed for driving an air blower, and a controller electrically connected to the flow rate sensor and the power sensor and configured to determine whether the air supply system has a fault by using the air flow rate measured by the flow rate sensor and the power consumption measured by the power sensor.
