Lowering the operating temperature of solid oxide fuel cells (SOFCs) is essential for realizing their potential in the stationary and portable energy space. Synthesis of SOFCs using thin‐film electrolytes enables high‐performance devices at reduced temperatures and unique processing capabilities. A nanoscale compositionally graded electrolyte developed by K. Kerman et al. on page 656 using a co‐sputtering fabrication method provides selective interfacial functionality and synergistically combines the advantages of multiple materials. An atomistic model of such a structure is shown in the image.
