Abstract: 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.

Abstract: A method for establishing and/or improving a simulation model of an electrolyzer plant includes predicting one or more prediction values of at least one quantity; obtaining one or more measurement values of the same at least one quantity that relate to the same given operating state of the electrolyzer plant; determining at least one deviation of the one or more prediction values from the respective measurement values; determining from the deviation and the simulation model a contribution and/or an adjustment to the simulation model; and applying the contribution and/or the adjustment to the simulation model.
