Abstract
The invention provides a solid electrolyte separator for separating two electrodes from each other in an electrochemical cell. The separator is of composite layered construction and comprises at least one porous layer of solid electrolyte material having a plurality of interconnected channels or pores in its interior and opening out of its surface, and a dense layer of non-porous solid electrolyte material. The layers are integrally bonded together, face-to-face, and each porous layer is an outer layer of the separator.
