1. An assembly for an electrochemical system, the assembly comprising:
a separator plate with at least one layer, and
a membrane electrode assembly (MEA) comprising:
an electrochemically active region,
a frame-like reinforcing layer surrounding the electrochemically active region, and
at least one tab for positioning the MEA relative to the separator plate and/or for fastening the MEA to the separator plate,
wherein the at least one layer of the separator plate has a first flat side and a second flat side opposite the first flat side,
wherein the tab is connected at one side to the frame-like reinforcing layer and a free end of the tab is arranged on the side of the second flat side of the at least one layer of the separator plate,
wherein the frame-like reinforcing layer is arranged on the first flat side of the at least one layer of the separator plate,
wherein the tab is formed integrally with the frame-like reinforcing layer, and
wherein at least one incision or recess is provided in the frame-like reinforcing layer, and the incision or recess delimits a border of the tab.
