Formation of a waterproof sintered ceramic electrolyte layer on a metal sheet substrate for solid oxide fuel cell

摘要

A method of forming a waterproof sintered ceramic electrolyte layer of a solid oxide fuel cell, said method comprising the steps of: depositing a ceramic powder on a stainless steel sheet substrate or on top of an intermediate layer of ceramic electrode porous on said substrate, by using electrophoretic deposition to form a deposited ceramic powder layer; isostatically pressing said deposited ceramic powder layer to form a compressed ceramic powder layer; and heating said compressed ceramic powder layer to a temperature below 1100 ° C to sinter said compressed ceramic powder to form said sintered ceramic electrolyte layer on said substrate.
