1. An interconnector for a stack of solid oxide cells of the SOEC/SOFC type operating at high temperature, intended to be arranged between two adjacent electrochemical cells of the stack, each electrochemical cell being formed of a cathode, of an anode and of an electrolyte intercalated between the cathode and the anode, the interconnector including:
a flat face whereon at least one first group of identical first elements in relief with respect to the flat face and a second group of identical second elements in relief with respect to the flat face are formed,
the first elements in relief having different geometric features with respect to the second elements in relief,
the height of each first element in relief, measured as being the largest vertical dimension of the first element in relief with respect to the flat face, being different from the height of each second element in relief, measured as being the largest vertical dimension of the second element in relief,
the contact width of each first element in relief, measured as being the largest horizontal dimension with respect to the flat face of the outer contact end of each first element in relief, opposite the inner end in contact with the flat face and intended to be in contact with an electrochemical cell, being different from the contact width of each second element in relief, measured as being the largest horizontal dimension of the with respect to the flat face of the outer contact end of each second element in relief, opposite the inner end in contact with the flat face and intended to be in contact with an electrochemical cell; and
a metal alloy substrate having two main flat faces, one of the main flat faces comprising a first coating layer forming a first contact layer with an electrochemical cell, the other of the main flat faces comprising a second coating layer forming a second contact layer with an electrochemical cell,
the first coating layer and/or the second coating layer comprising a flat face and elements in relief formed thereon.
