1. An electrochemical system having at least one electrochemical device comprising:
a stack of n solid oxide electrochemical cells, n being an integer greater than or equal to 1, and at least n−1 interconnect plates interposed between the electrochemical cells,
means for supplying gas to the electrochemical cells and means for collecting gases produced by the electrochemical cells,
means for electrically connecting the system to the exterior,
heating means using Joule effect, the heating means being inserted into at least one heating plate, and the at least one heating plate being disposed on the stack,
two clamping plates each disposed at one end of the stack in a direction of the stack, the at least two clamping plates being a distinct element from the stack, and
tie rods passing through the clamping plates configured to apply a clamping force to the n cells and n−1 interconnects, wherein
the heating means are disposed so that heating of the stack takes place through at least part of at least one clamping plate, and
the at least one heating plate is in contact with an external face of the at least one clamping plate, the at least one heating plate being in contact with the external face of said at least one clamping plate and the at least one clamping plate being two distinct elements.
