7 Preparation of LaGaOs Thin-Film Electrolytes for Application at Temper atnres Lower Than 773 K 

Operating temperatures below 973 K are preferred to use metallic SOFC components (e.g., interconnects) and reduce the start-up time. Decrease of the operating temperature can be achieved by using LaGaOg thin films. In this section, the preparation of LSGM films is briefly described, and performance of SOFC cells using the LSGM thin-film electrolytes is discussed.
