Fabrication of zirconia electrolyte films by electrophoretic deposition

摘要

A method for deposition of an electrolyte material on a porous substrate in which a suspension of particles having a controlled surface charge and suitable for use as an electrolyte is formed and the porous substrate, which is made of an electrode material is immersed. A voltage is applied across the suspension between an electrode in contact with the suspension and the porous substrate, whereby at least a portion of the particles migrate toward the porous substrate and are deposited on the porous substrate.
