Power conversion unit useful for electrochemical energy conversion, comprises base plate, cover plate, a plate stack, which is arranged between the base plate and the cover plate, and a pressure cushion

摘要

Power conversion unit (1) comprises at least one base plate (2), at least one cover plate (3), a plate stack (4), which is arranged between the base plate and the cover plate, and at least one pressure cushion (5). An independent claim is also included for using the power conversion unit, comprising compensating the deformation of at least one base plate, at least one cover plate and/or plate stack using at least one pressure cushion under operating conditions, and/or compensating the expansions and/or compressions of clamping elements by using at least one pressure cushion.
