PRESSURISED ELECTROCHEMICAL REACTOR

An electrochemical reactor, configured to receive a stack, the reactor including a support plate, the stack being positioned in contact with the support plate, wherein the reactor further includes a dome, having an internal volume (V), intended to receive the stack, of the liquid glass frit having a volume (V) and an upper face called free surface, and configured to cover the stack, the internal volume further including a cover gas positioned in contact with the free surface of the liquid frit volume, the cover gas being configured to be pressurised by a module at a clamping pressure (Ps), this being configured so as to maintain the stack compressed on the support plate, under a mechanical force proportional to the clamping pressure.
