System for accommodating electrochemical cell stacks

Method for accommodating at least one electrochemical cell stack (10A, 10B) in a system (100), the system (100) having

• a compression system (30) with tensioning means (32) mechanically connected to opposite ends of the at least one electrochemical cell stack (10A, 10B), for applying a compression force on the electrochemical cells in the stacking direction (S),
• the method comprising the steps of:
• providing a housing (20) surrounding the at least one electrochemical cell stack (10A, 10B), for thermally and fluidly separating an inside and an outside of the housing (20);
• wherein providing, for each of the tensioning means (32), an internal liner (23) extending through the housing (20) in a stacking direction (S) of the at least one electrochemical cell stack (10A, 10B), wherein the internal liners (23) 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), and
• arranging each of the tensioning means (32) through one of the internal liners (23), for applying the compression force of the compression system (30) on the at least one electrochemical cell stack (10A, 10B).
