Method for depositing layer of ceramic material onto a metallic support for solid oxide fuel cells

A method for depositing at least one layer of material on a metallic support for solid oxide fuel cells comprising an electrolyte, wherein said metallic support comprises a porous metallic material comprising single sintered grains, comprising the steps of:

• preparing a surface of the metallic support, said metallic support comprising the porous metallic material comprising the single sintered grains;
• preparing an apparatus for an electrolytic bath comprising an anode and a cathode, with relative actuation means of the apparatus, containing an aqueous solution with cations necessary to obtain a layer of ceramic material;
• dipping the metallic support in said electrolytic bath;
• controlling said actuation means of the electrolytic bath so as to apply a current between the anode and the cathode of said bath, said current causing the deposition, in a selective manner, of the ceramic material on the surface of the metallic support, until said layer of ceramic material is made,
• wherein said layer of ceramic material comprises a ceramic material with anti-corrosion protection properties,
• and wherein said layer of ceramic material is deposited onto the surface of the single grains of the metallic support,
• wherein said layer of ceramic material comprises cerium oxide or a mixture of cerium oxide and metallic oxide, which constitutes an effective barrier to the interdiffusion of elements between said metallic support and said electrolyte;
• and
• depositing, by means of the apparatus for electrolytic bath, a further layer, made in a mixture of nickel and cerium oxide, which constitutes an anode of the fuel cell, onto said layer of ceramic material,
• wherein said anode is deposited following the porosity of said metallic support.
