METHOD OF FABRICATING CONTACT ELEMENTS IN AN ELECTROCHEMICAL DEVICE SUCH AS SOFC OR EHT
The invention relates to a method of fabricating a contact element in an electrochemical device (9) such as an SOFC or an EHT which comprises the following steps: a) use is made of: at least one cell (8) consisting of an assemblage made up of an electrode to be hydrogenated (5) - electrolyte (4) - electrode to be oxygenated (3); at least one first interconnector (1); and at least one second interconnector (7); b) at least one layer of a conducting material is deposited on the first interconnector (1) and/or the second interconnector (7); c) an electrochemical device (9) is assembled; said method being characterized in that: d) a thermomechanical treatment is carried out on the electrochemical device obtained on completion of step c). The invention also relates to an electrochemical device (9) equipped with at least one contact element (2) obtained according to this fabrication method.
