Beschreibung
Zusammenfassung:	An electrical energy system includes fuel cells and a battery, as well as a DC converter arranged between the fuel cell and the high-voltage battery, wherein the DC converter is a buck-boost converter, having two series-connected semiconductor switches in one of its two current pathways, between which an inductance is connected, which joins the two current pathways of the DC converter. A related method for operating an electrical energy system for a motor vehicle is also provided.
