An electrical energy system containing fuel-cells and a method for operating an electrical energy system for a motor vehicle are disclosed. The electrical energy system includes, for example: at least one fuel-cell; at least one HV battery; a diode arranged between the at least one fuel-cell and the at least one HV battery, which diode allows current flow only in a direction from the at least one fuel-cell to the at least one HV battery; a switching element configured to reversibly disconnect or close a circuit between the at least one fuel-cell and the at least one HV battery; a control unit configured to control the switching element; and an inductor arranged between the at least one fuel-cell and the at least one HV battery and connected in series with the switching element.
