The invention relates to a component () comprising a substrate made of chromia-former metal alloy (), the basic element of which is iron (Fe) or nickel (Ni), wherein the substrate has two main planar faces. According to the invention: one of the main planar faces is coated with a coating comprising a thick layer of ceramic (), grooved to delimit channels () suitable for the distribution and/or collection of gases, such as HO water vapour, Hor air, and/or one of the main planar faces is coated with a thick metal layer (), grooved to delimit channels () suitable for the distribution and/or collection of gases, such as HO water vapour, H, Oor draining gas. The invention also relates to the associated production processes.

Component constituting an HTE electrolyser interconnector or SOFC fuel cell interconnector and associated production processes

The invention relates to a method of fabricating a contact element in an electrochemical device () such as an SOFC or an EHT which comprises the following steps: a) use is made of: at least one cell () consisting of an assemblage made up of an electrode to be hydrogenated ()-electrolyte ()-electrode to be oxygenated (); at least one first interconnector (); and at least one second interconnector (); b) at least one layer of a conducting material is deposited on the first interconnector () and/or the second interconnector (); c) an electrochemical device () 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 () equipped with at least one contact element () obtained according to this fabrication method.
