Energy supply system for an underwater vehicle, method for operating a power supply system and underwater vehicle with such a power supply system

摘要

In a power supply system (4) for an underwater vehicle (1), in particular for a submarine or an unmanned underwater vehicle, comprising a fuel cell system (10) with pure hydrogen or with a hydrogen-containing gas as the first operating gas and with pure oxygen or an oxygen-containing Gas is operable as a second operating gas, and with an operating gas container (13) for one of the two operating gases, wherein the operating gas container (13) with the fuel cell system (10) is fluidically connected, the operating gas in the operating gas container (13) according to the invention in a supercritical state saved. As a result, Boil-off gas losses can be reduced and thus a long service life of the underwater vehicle can be made possible.
