Abstract

Self-Organizing Map (SOM) method was developed in order to investigate the fracture process of SOFC module under operating environments. The damage testing method was applied to ceria electrolyte-supported single cells. The vertical crack in the electrolyte and crack in the glass seal were detected by AE method. The SOM method identified two types of damage. By using this method, it was possible to show the possibility that the detailed deterioration process can be evaluated visually and in real-time, even when applied to modules at the actual equipment level.
