Abstract

The invention is about an electrochemical energy conversion system (1), with electrochemical cells (2), each electrochemical cell (2) comprising a membrane electrode assembly (3) arranged between a cathodic gas diffusion layer (4) and an anodic gas diffusion layer (5) and on front sides (6) surrounded by a frame (7) and enclosed between bipolar plates (8), the electrochemical cells (2) being compressed between first and second end plates (9, 10) by means of tie rods (11), wherein a pressure unit (12) is arranged between the second end plate (10) and a third end plate (13) opposite the first end plate (9) in relation to the second end plate (10), the pressure unit (12) comprising a piston (14) that acts on the electrochemical cells (2) through an opening (15) in the second end plate (10) and the directly neighbouring bipolar plate (8), the piston (14) having an attachment (16) for different pressure profiles.
