Das vorliegende System verwendet einen Wasserelektrolysestapel, um Wasser in Wasserstoff und Sauerstoff aufzuspalten. Der Wasserstoff wird an der negativen Elektrode abgeleitet und in einem Wasserstofftank gespeichert, während der Sauerstoff an der positiven Elektrode abgeleitet und in einem Sauerstofftank gespeichert wird. Die gespeicherten Gase können bei Bedarf in den Elektrolysestapel zurückgeführt werden. Sensoren messen die Wasserstoff- und Sauerstoffkonzentration in dem abgeleiteten Fluid, und eine Steuerung vergleicht diese Messwerte mit sicheren Grenzwerten. Ist die Konzentration zu hoch, werden Ventile automatisch eingestellt, um den Durchfluss der gespeicherten Gase zu steuern. Zusätzliche Komponenten wie ein Ejektor und Druckregler tragen zu einem effizienten Betrieb bei und verhindern eine gefährliche Gasansammlung.
