AIR SUPPLY PRESSURE SETPOINT DETERMINATION FOR A FUEL CELL POWER MODULE

摘要

An air control system and method for a fuel cell system includes a manifold, a air delivery device that supplies air to the manifold, and a plurality of fuel cell components. A plurality of flow controllers (FCs) control airflow from the manifold to the fuel cell components. A controller communicates with the FCs and the air delivery device and generates a manifold pressure setpoint based on a first factor that is related to fuel cell system stability and a second factor that is a based on minimum and maximum pressures of the air delivery device for a predetermined airflow. If the first and second factors are met, the controller optionally generates the manifold pressure setpoint based on a third factor that is related to fuel cell system efficiency.
