    Abstract: A fuel cell system having a fuel cell control module (FCU) and a method of controlling the same are provided. The method includes selecting one of at least one control parameter and learning system efficiency at each of at least one configurable candidate value of the selected control parameter based on supplied current by driving the fuel cell system. Additionally, the method includes determining a value of the selected control parameter by comparing the system efficiency at each of the at least one configurable candidate value of the selected control parameter with system efficiency corresponding to an initial performance index, at each of at least one predetermined representative current point. Thereby, efficiency of the fuel cell system is improved.

    Abstract: Disclosed is a system and method for controlling a fuel cell system. More specifically, a fuel cell demand current is calculated based on a driver demand current calculated from a driver demand torque. Then a target flow rate-1 of air to be supplied to a fuel cell stack is calculated based on the fuel cell demand current and a target stoichiometric ratio (SR) of air. The target flow rate-1 is then compensated for using the target SR, an RPM command value of an air blower is calculated based on a compensated target flow rate-2 and the amount of air currently measured. The operation of the air blower is subsequently controlled based on the calculated RPM command value.

    Abstract: A method and a system are provided for controlling an air intake of a fuel cell vehicle. The method includes calculating a value for basic air intake of a fuel cell based on a driver requirement and calculating a value of motor current requirement based on the driver requirement. A rate-of-change is calculated of the value of motor current requirement and a value for supplementary air intake is calculated by multiplying the rate-of-change of the value of motor current requirement by a gain value. A value for final air intake is then calculated by adding the value for basic air intake and the value for supplementary air intake. An air blower of an air intake system of the fuel cell is operated with the value for final air intake.
