Zusammenfassung:The invention relates to a method for producing a stack formation (60), of a battery or fuel cell from single layers in film or leaf form (12, 14, 16), wherein at least the following method steps are performed: a) creating single layers (12, 14, 16) with an outer contour (46) by perforation (32) in at least one perforating direction (34, 36) in a material in web form (74, 76, 78) for single layers (12, 14, 16) of one type at a time; b1) making the perforation (32) in such a way that tear-away edges (50), and serving as predetermined breaking points, of perforation ties (40) lie within the outer contour (46); b2) making the perforation (32) in such a way that it has the effect of forming temporary supporting structures (52) between the single layers (12, 14, 16) in the respective material in web form (74, 76, 78); c1) separating individual, identical single layers (12, 14, 16) from one another at the predetermined breaking points of the perforation ties (40) lying within the outer contour (46) of the single la
