System til konditionering af en flerhed af stablede understabler af fastoxidceller af høj temperatur-SOEC/SOFC-typen

A system may condition a plurality of sub-stacks of high-temperature SOEC/SOFC-type solid oxide cells forming a modular stack. Such a system may include: a thermal enclosure; a plurality of sub-stacks; a plurality of end plates, each having an upper face and a lower face, the surface of an upper face being of greater dimension than the surface of a lower face of a sub-stack, and the surface of a lower face being of greater dimension than the surface of an upper face of a sub-stack so as to obtain one or more free surfaces which are not superimposed with a sub-stack; a plurality of die-forming supports, including a recess; a plurality of flexible elements above a recess; a plurality of bearing elements capable of coming into contact with a flexible element so as to deform it.
