    , the pores forming a plurality of ion-transfer passages extending laterally between the opposite surfaces for transferring oxygen-ions laterally within the layer, the layer having an electronic insulating composition around said pores composed of a metallic oxide with the formula
    
    
    space="preserve" listing-type="equation">T.sub.a X.sub.b O.sub.cwherein T is a transition metal, X is at least one metal selected from the group consisting of a transition metal, Al, Sn, and an alkali metal, and the integers a, b and c represent the number of atoms to balance the formula, said layer having a density of about 2-5 gm/cc, being essentially gas-tight and stable at temperatures above about 200°
