VARIABLE PEM FUEL CELL SYSTEM START TIME TO OPTIMIZE SYSTEM EFFICIENCY AND PERFORMANCE

摘要

A system and method for controlling a fuel cell system start time based on various vehicle parameters. The method includes providing a plurality of inputs that identify operating conditions of the fuel cell system and determining a maximum allowable start-time of the fuel cell system using a hybridization control strategy and the plurality of inputs. The method then determines a maximum compressor speed and ramp rate to provide the optimal allowable start-time of the fuel cell system minimizing energy consumption and noise.
