7 . The method as claimed in claim 6 , wherein, during assembly, the first and/or the second stack component ( 140 ) is positioned via the corresponding first adjustment opening ( 115 ) and is aligned via the corresponding second adjustment opening ( 125 ).
8 . The method as claimed in claim 6 , wherein, for assembly of the second stack component ( 140 ), the respective adjustment device ( 110 , 120 ) and the respective adjustment opening ( 115 , 125 ) are dimensioned with a first clearance fit.
9 . The method as claimed in claim 8 , wherein, for assembly of the first stack component ( 140 ), there is a second clearance fit between the respective adjustment device ( 110 , 120 ) and the respective adjustment opening ( 115 , 125 ) of the plurality of stack components of the electrochemical substack below the second stack component ( 140 ), and the first clearance fit is dimensioned to be tighter than the second clearance fit.
