ABSTRACT:
A method of preparing a membrane is disclosed, which includes the step of impregnating an inorganic proton-conductive material into matrices of porous ceramic membranes. The inorganic proton-conductive material may include an inorganic poly-acid, such as polyphosphates or poly-antimonic acids. The inorganic proton conducting material may include Zr (zirconium).
The invention further provides a porous ceramic membrane, which includes an inorganic proton-conductive material impregnated into a porous ceramic membrane matrix.
The ceramic membrane may be a tubular ceramic membrane, which includes pores with a diameter of at least 0.3 .mu.m, and depositions of electroconductive coatings onto its surface on which externally applied potential can be applied as a driving force for hydrogen separation.
