US 5,059,497 A · Composite ion-conductive electrolyte member

Abstract

A solid, composite, ion-conductive electrolyte member comprised of first and second layers which are bonded together, with the first layer being constituted of an ion-conductive material such as glass or polycrystalline ceramic, e.g., ANL glass or beta-type alumina, and the second layer being preferably constituted of a material selected from the group consisting of the titanium oxide family, most preferably, rutile (TiO.sub.2), and its related suboxides (Ti.sub.N O.sub.2N-1, where N is any selected number from 4-10, inclusive). The first and second layers are preferably intimately bonded together by means of an electrophoretic deposition process, a chemical vapor deposition process, a plasma spraying deposition process, a pyrolitic deposition process, or a pressing and sintering process.

Dependent claims

An electrochemical cell including:

an anode containing anodic reactants;
a cathode containing cathodic reactants;
a composite ion-conductive electrolyte member, including:
a first layer constituted of an ion-conductive material;
a second layer bonded to said first layer, said second layer being constituted of an electrically conductive material which is highly resistant to the anodic reactants of the cell, and which is sufficiently porous to allow flow of anodic reactants to contact said first layer;
and,
wherein said first layer is disposed in contact with the cathode of the cell, and said second layer is disposed in contact with the anode of the cell.
