Patent ID: 7780936

Claim:
A process for manufacturing an electrochemical device comprising: providing a cathode, an anode, and at least one electrolyte membrane disposed between said anode and said cathode, wherein each of said cathode, anode, and the electrolyte membrane comprises at least one ceramic material, and wherein the process of providing at least one of the cathode, the anode, and the electrolyte membrane includes: thermally treating an aqueous solution comprising at least one metal cation, at least one hydrosoluble ethylenically unsaturated monomer with an ester moiety, and a hydrosoluble cross-linking monomer with at least two ethylenically unsaturated ester moieties to obtain a gel; calcining said gel to remove organic substances and to form at least one crystalline metal oxide in a nanosize powder; and sintering said powder to provide the ceramic material.
