Abstract

A method of making an electrolytic cell in which an electrolyte layer of an intermediate sintered form is coated with a pre-coat layer containing electrically non-conductive particles of less than about one-tenth of a micron in size to fill in defects existing within the electrolyte layer. The pre-coat layer is removed so that the electrically non-conductive particles remain within the defects of the electrolyte layer. The cathode layer is then applied to the electrolyte layer with the electrically non-conductive particles in place within the defects. The intermediate sintered form is fired with the applied cathode layer to produce the electrolytic cell.
