A thin layer of a vertically aligned nanocomposite structure is deposited between the electrolyte, Ce0.9Gd0.1O1.95 (CGO), and the thin film cathode layer, La0.5Sr0.5- CoO3 (LSCO), of a thin-film solid-oxide fuel cell (TFSOFC). The maximum power density of the single cell with the interlayer varied with temperature from 329 to 812 mW cm−2 at 550 and 700 °C, respectively (see figure), which demonstrates superior cell performance compared to the cells without the interlayer.
