Abstract

Bipolar plate (10) for an electrochemical cell, the bipolar plate comprising:- one main sheet (12) defining a plane, said horizontal plane (H), and- at least one spring sheet (14) shaped such that it defines:. upper peaks (20) and lower peaks (40) alternately distributed along the horizontal plane (H), the spring sheet (14) being deformable between a compressed state and an uncompressed state such that the distance in the vertical direction between the upper peaks (20) and the lower peaks (40) is variable,. connection sections (60) connecting one upper peak (20) to one lower peak (40),each connection section (60) includes one horizontal part (62) which is parallel to the horizontal plane (H) when the spring sheet (14) is in the uncompressed state, the horizontal parts (62) being positioned between the upper (20) and the lower (40) peaks with respect to the vertical direction.
