THIN METAL OXIDE FILM AND METHOD OF MAKING THE SAME ESPECIALLY FOR FUEL CELLS

摘要

A method for making a thin metal oxide film (10), comprising the steps of: preparing a first solution having at least one metal salt dissolved therein; preparing a second solution having a water soluble polymer dissolved therein; combining the first solution and the second solution at a predetermined ration to form a third solution; deposing a layer (14) of the third solution on a substrate (12); and heating the substrate (12) having the third layer (14) thereon at a temperature sufficient to oxidize the at least onemetal salt to form the thin metal oxide film (10). The method is useful for forming electrolytes or electrodes in fuel cells.
