Abstract
The subject matter described herein relates to a method for filling fluid containers, in particular fluid containers for fuel cells The method includes: providing a pressure chamber having a pressure chamber interior; positioning a fluid container within the pressure chamber interior in such a manner that a holding space of the fluid container is fluidically connected to the pressure chamber interior; evacuating the pressure chamber interior up to a target negative pressure in such a manner that, due to the fluid coupling, a negative pressure difference initially forms in the pressure chamber interior with respect to the holding space; and filling the fluid container by introducing a fluid into the holding space.
