Separator plate with a bead passage

A separator plate for an electrochemical system, comprising a first individual plate and a second individual plate, which are connected to each other, wherein at least the first individual plate comprises:

• an electrochemically active region,
• at least one through-opening for the passage of a fluid, having an inner edge that bounds the through-opening,
• a sealing bead arranged around the through-opening for sealing off the through-opening, wherein the sealing bead has a sealing bead interior, a first bead flank facing towards the through-opening, and a second bead flank
• a plurality of first conveying channels, which adjoin the first bead flank of the sealing bead, are in fluid connection with the sealing bead interior, extend from the sealing bead in the direction of the through-opening, and are fluidically connected to the through-opening via at least one first aperture formed in the separator plate, wherein the through-opening and the sealing bead interior are fluidically connected to each other via the first conveying channels and the at least one first aperture, and
• a first weld, surrounding the through-opening, for connecting the two individual plates, wherein the first weld is at a smaller distance from the inner edge than the at least one aperture and/or the first conveying channels.
