The invention relates to a drive system including energy recovery for driving a machine, in particular for driving a crane. Said drive system comprises at least one fuel cell unit, at least one capacitive energy storage unit, and at least one driving motor. The fuel cell unit and the energy storage unit are connected in parallel and feed at least one driving motor. According to the invention, the capacitive energy storage unit is dimensioned in such a way that the differential voltage between the fuel cell unit and the capacitive energy storage unit during operation is minimized to such an extent that the current that is caused by the voltage and flows within the parallel connection between the fuel cell unit and the energy storage unit does not exceed a defined safety limit, the fuel cell unit and the energy storage unit being directly coupled to each other and to the remaining driving components without using a DC/DC converter. The invention further relates to a machine comprising the drive system of the invention. |
