Method for Operating a Plurality of Electrolyser-Stacks

A method for operating a plurality of electrolyzer-stacks includes determining a concentration of impurities, which is originated by a second reaction gas electrochemically produced at a second electrode type of each of the electrolyzer-stacks, within a first gas stream; generating a trigger signal...

Beschreibung
Zusammenfassung:	A method for operating a plurality of electrolyzer-stacks includes determining a concentration of impurities, which is originated by a second reaction gas electrochemically produced at a second electrode type of each of the electrolyzer-stacks, within a first gas stream; generating a trigger signal if the concentration of the impurities of the second reaction gas within the merged first reaction gas exceeds a specific second reaction gas level; identifying at least one electrolyzer-stack out of the plurality of electrolyzer-stacks, which is low performing in respect to excessively feeding second reaction gas impurities into the first gas stream, by measuring a current density of at least one electrolyzer-stack of the plurality of electrolyzer-stacks, if the trigger signal is generated.
