Abstract: A ceramic membrane having a non-zero volume and including:
a) a dense layer, having opposed faces of areas S and S′ and having a non-zero thickness e, of a solid electrolyte;
b) two porous electrodes, which are hybrid conductors and have non-zero thicknesses e1 and e′1, which are identical or different, coated on non-zero areas s1 and s′1, which are identical or different, of the two opposed faces of areas S and S′ of the solid electrolyte;
c) two porous current collectors, of non-zero thicknesses, e2 and e′2, which are identical or different, coated on non-zero areas s2 and S′2, which are identical or different, of the two porous electrodes; and
d) at least one porous covering layer, of non-zero thickness e3, coated on a non-zero area s3, of at least one of the collectors, a thickness E of the membrane is equal to the sum of the thickness of each of the elements a)-d).
