1. An electrochemical device comprising:
an electrochemical unit having a shape, and
a containment chamber housing the electrochemical unit in an inner volume, the inner volume being delimited by an inner surface of the containment chamber, said inner surface conforming with the shape of the electrochemical unit,
wherein said electrochemical unit comprises:
an SOEC/SOFC-type solid oxide stack operating at high temperature,
a clamping system provided with two clamping plates including a first clamping plate and a second clamping plate between which the stack is clamped, at least one of the first and second clamping plates comprises at least one gas inlet and at least one gas outlet;
gas distribution and discharge means for operation of the stack cooperating, respectively, with the at least one gas inlet and the at least one gas outlet, and
heating means configured to provide the heating of the electrochemical unit, said heating means being disposed in an internal volume of said electrochemical unit so as to be integrated in said electrochemical unit,
wherein the containment chamber comprises a floor whereon the electrochemical device rests, walls, and a roof, and
wherein a space between the inner surface of the containment chamber and a periphery of the electrochemical unit is between 5 mm and 10 mm.
