The present invention is concerned with methods for the deposition of ceramic films on ceramic or metallic surfaces, particularly the deposition of sub-micron thickness ceramic films such as films of stabilised zirconia and doped ceria such as CGO (cerium gadolinium oxide). The present invention is particularly useful in the manufacture of high and intermediate temperature operating fuel cells including solid oxide fuel cells (SOFC) and also metal supported intermediate temperature SOFC operating in the 450- 650 °C range.

La présente invention concerne des procédés pour le dépôt de films céramiques sur des surfaces céramiques ou métalliques, et notamment le dépôt de films céramiques d'épaisseur submicrométrique tels que des films de zircone stabilisée et d'oxyde de cérium dopé, par exemple de CGO (oxyde de cérium-gadolinium). La présente invention est particulièrement utile pour fabriquer des piles à combustible à température élevée ou intermédiaire, telles que des piles à combustible à oxyde solide (SOFC), ainsi que des SOFC à température intermédiaire supportées sur métal fonctionnant dans une plage comprise entre 450 et 650°C.
