Abstract

In this study, Ni-Gd0.1Ce0.9O1.95 (GDC) anode-supported ceria electrolyte film was prepared by a citrate sol-gel route. A simulated environment testing method which was combined with acoustic emission (AE) monitoring was developed to investigate the electrochemical performance and fracture process of a fuel cell Ni-GDC/Sm0.2Ce 0.8O1.9 (20SDC)/La0.6Sr0.4Co 0.2Fe0.8O3-δ (LSCF) based on this thin film with thickness of 500 nm. The damage testing method was applied o anode-supported thin creia electrolyte single cells. The results showed that the AE monitoring detected the fracture process at cell performance temperatures of 700-900°C, which showed the delamination of LSCF cathode from the SDC electrolyte film, which presented a drastic decrease of electrical performance. It was demonstrated that the AE monitoring conducted in this study was useful to detect and analyze the fracture process of the single cell with the electrochemical measurement.
