Abstract
The present invention relates to an alkaline cation-conducting ceramic membrane covered, over at least a portion of the surface thereof, with a cation-conducting organic polyelectrolyte layer that is insoluble and chemically stable in pH-basic water. The invention also relates to an electrochemical device including such a membrane as a solid electrolyte in contact with a liquid electrolyte formed of an alkali metal hydroxide aqueous solution.
