1. An assembly for an electrochemical system, comprising:
a first separator plate;
a second separator plate; and
a membrane electrode assembly (MEA) arranged between the separator plates for forming an electrochemical cell between the separator plates, the MEA comprising:
an electrochemically active region;
at least one frame-like reinforcing layer surrounding the electrochemically active region;
at least one through-opening for the passage of a fluid formed in the reinforcing layer and in each separator plate, wherein the through-opening of the reinforcing layer and the through-openings of the separator plates are arranged in alignment with one another so as to form a fluid line portion;
a flexible tab of the reinforcing layer with a free end extending from an edge of the least one through-opening radially inward into the least one through-opening for influencing a fluid flow; and
a projection area defined by an orthogonal projection of at least one of the two through-openings of the separator plates onto the reinforcing layer, wherein the projection area at least partially overlaps with the tab.
