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° C. to about 100° C. to produce a dry primary SOFC layer. The dry primary SOFC layer is then cooled at a rate less than about 5° 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° C. then quenching to a temperature from about 10° C. to about 30° C. to produce an infiltrated SOFC layer.
