Patent ID: 8642200

Claim:
A fuel cell system, comprising: a fuel cell stack having an anode inlet and a cathode inlet; an air compressor in fluid communication with the cathode inlet; at least one sensor adapted to measure a surge indicator; and a controller in electrical communication with the at least one sensor and configured to adjust an adaptable compressor map in response to the measured surge indicator and establish an operating setpoint of the air compressor based thereon, the adaptable compressor map having a surge line and a surge control distance (SCD), wherein the controller is operable to: establish an initial operating setpoint for the air compressor based on the adaptable compressor map; monitor the surge indicator; adjust the adaptable compressor map based on the monitored surge indicator; determine a desired operating setpoint based on the adjusted adaptable compressor map; and establish an adapted operating setpoint for the air compressor based on the adaptable compressor map following the adjustment thereof.
