METHOD FOR CONTROLLING FUEL CELL OUTPUT OF FUEL CELL HYBRID VEHICLE

摘要

PURPOSE: A method for controlling a fuel cell output of a fuel cell hybrid vehicle is provided to improve fuel efficiency of the fuel cell hybrid vehicle by maximizing an amount of energy recovery in a regenerative braking process. CONSTITUTION: If the electric energy of a super cap is above a preset value, a direct connection switch is turned off(S32,S33). A constant current operation of the fuel cell starts(S34). The constant output control of the fuel cell accessories is performed(S35). The regenerative braking of the fuel cell hybrid vehicle is determined(S37). If the electric energy of the super cap is above the preset value, the generation of the fuel cell is stopped(S42).
