SYSTEM FOR ACCOMMODATING ELECTROCHEMICAL CELL STACKS

The present invention relates to a system (100) for accommodating electrochemical cell stacks (10A, 10B) comprising a housing (20) and a compression system (30) for applying a compression force on the electrochemical cells in the stacking direction (S). According to the invention, the system (100) comprises internal liners (23) extending through the housing (20) in a stacking direction (S) having open ends to the outside of the housing (20), for separating a gas volume (y) inside the liners (23) from an inner space gas volume (x) of the housing (20); wherein each of the tensioning means (32) of the compression system (30) extends through one of the liners (23).
