SEPARATOR PLATE AND ELECTROCHEMICAL CELL

A separator plate for an electrochemical system, comprising a first and a second metal layer arranged with flat sides adjacent to each other. The first and the second metal layer each having at least one through-opening for supplying and/or discharging a fluid. Circumferential edges of the through-openings are formed at least in part by a half-bead. An open edge of the half-bead is angled so as to form a collar.
