FUEL CELL SYSTEM AND METHOD FOR REGULATING A FUEL CELL SYSTEM

摘要

The invention relates to a fuel cell system for mobile applications, comp rising a fuel cell (1) and a DC/DC converter (2) which is coupled to the fue l cell and which can be coupled to an energy store (3). The fuel cell system is characterized in that a control/regulation unit (4) is connected to the fuel cell (1) and to the DC/DC converter (2) and that the control/regulation unit (4) comprises a performance characteristics regulator (5) that receive s a value lBz,ist of a current, a voltage value UBz,ist from the fuel cell ( 1) and a value for at least one additional operating variable of the fuel ce ll system, that processes the received values lBz,ist, UBz,ist and the value for the operating variable to give a control signal and that forwards the c ontrol signal to a device (6) for controlling the operating variable. The in vention also relates to an active hybrid system and to a method for the perf ormance characteristic regulation of the fuel cell.
