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.
Claims15
A method for filling fluid containers, the method comprising the steps of:
- 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;
- switching from an evacuation state into a filling state, in which a fluidic exchange between the holding space of the fluid container and a fluid tank that is fluidically connected to the holding space is permitted;
- and
- filling the fluid container by introducing a fluid into the holding space.
A system for filling fluid containers, the system comprising:
- a pressure chamber that comprises a fluid-tight pressure chamber interior;
- a fluid container, which is positioned within the pressure chamber interior, and a holding space of which is fluidically connected to the pressure chamber interior;
- a compressor device that is embodied so as to generate a negative pressure difference in the pressure chamber interior with respect to the holding space;
- a fluid tank, which is fluidically connected to the holding space in order to introduce a fluid into the holding space;
- and
- a controllable multiport valve that is fluidically connected to the fluid container and is embodied so as to switch from an evacuation state into a filling state, in which a fluidic exchange between the holding space of the fluid container and the fluid tank is permitted.
