LSM/YSZ (Strontium substituted Lanthanum Manganite/Yttria Stabilised Zirconia) SOFC (Solid Oxide Fuel Cell) composite electrodes were fabricated with slurry spraying on both sides on either pure YSZ electrolyte foils or YSZ electrolyte foils with a CGO (Cerium-Gadolinium Oxide) barrier layer made by spin coating. Electrochemical impedance spectroscopy (EIS) was used to evaluate the performance of the LSM/YSZ composite electrodes. It was shown that the CGO barrier layer affects both the performance of the LSM/YSZ composite electrodes and the series resistance of the cells. This indicates that the cathode-electrolyte interface and the barrier layer-electrolyte interface have a large influence on the performance of LSM/YSZ composite electrodes.
