Abstract: A method for operating a drive unit operated with gaseous fuel. The gaseous fuel is provided under high pressure in a plurality of pressure tanks that can be connected via a supply line and with a metering valve via which the gaseous fuel can be dispensed to the drive unit. One of the pressure tanks is designed as a high-load pressure tank which is only connected to the supply line when the drive unit is under high load, the pressure tanks in which a lower gas pressure prevails than in the high-load pressure tank simultaneously being disconnected from the supply line.

Abstract: The invention relates to a fuel cell (2), comprising at least one membrane-electrode unit (10) having a first electrode (21) and a second electrode (22), which are separated from each other by a membrane (18), and at least two bipolar plates (40), which connect the membrane-electrode unit (10) on both sides, wherein the bipolar plates (40) are penetrated by a first supply channel, for supplying a fuel, and by a second supply channel, for supplying an oxidation means, wherein a first distribution structure (50) facing the first electrode (21) connects to a first edge of the first supply channel, and a second distribution structure (60) facing the second electrode (22) connects to a second edge of the second supply channel. The first electrode (21) extends along the membrane (18) in a region which is spaced apart from the first edge of the first supply channel, and the second electrode (22) extends along the membrane (18) in a region which is spaced apart from the second edge of the second supply channel.
