METHOD FOR ELECTROPHORETIC DEPOSITION OF A SOLID ELECTROLYTE LAYER ON NONCONDUCTING SUBSTRATES Russian patent published in 2022 - IPC C25D13/20 H01M8/10 

FIELD: chemical physics.

SUBSTANCE: invention relates to the field of electrophoretic deposition of a solid electrolyte layer on a non-conductive dense or porous substrate using a platinum sublayer and can be used for the manufacture of solid oxide fuel cells with a thin-film electrolyte. The deposition of a platinum sublayer on a non-conductive ceramic substrate is carried out from the deposition side of subsequent electrolyte layers by a drip method using a suspension in isopropanol of fine platinum powder with a concentration of 10-20 g/l, followed by drying at room temperature and sintering at a temperature of 850-1000°C for 1-1.5 hours.

EFFECT: obtaining a porous platinum coating tightly bonded to the substrate, which creates a high electrical conductivity of the substrate, making it possible multiple cycles of electrophoresis and sintering of the solid electrolyte layer.
