An assembly includes a solid-oxide pack of the SOEC/SOFC type and a system for clamping the pack. The assembly furthermore includes a coupling system gastight at high temperature, including a clamping base with a first through internal pipe to enable a tube to pass, a support base located in the pipe and having a second through internal pipe, and a seal, having a C shape, positioned against a first end of the support base. One of the clamping plates includes a through pipe for gas to pass having a support surface for the seal and a threaded countersink for receiving a thread of the clamping base.

An electrochemical device may be formed by assembly by stacking preassembled modules, each of these modules being produced as a usual stack of electrochemical cells. The manufacture of preassembled modules can make it possible to produce electrochemical devices with a large number of electrochemical cells, without the bracing problems present and excessive crushing courses that are encountered in the cell stacks according to the prior art, i.e., in a single block.
