Method for producing an infiltrated solid oxide fuel cell layer

Abstract:

A method of producing an infiltrated solid oxide fuel cell (SOFC) layer. The method begins by infiltrating a solution containing a solute into a SOFC layer to produce a primary SOFC layer. The primary SOFC layer is then dried in a heated environment, wherein the heated environment ranges in temperature from about 25.degree. C. to about 100.degree. C. to produce a dry primary SOFC layer. The dry primary SOFC layer is then cooled at a rate less than about 5.degree. C./min to room temperature to produce a cooled primary SOFC layer. The cooled primary SOFC layer is then heated to a temperature greater than 500.degree. C. then quenching to a temperature from about 10.degree. C. to about 30.degree. C. to produce an infiltrated SOFC layer.
