Abstract (in Japanese) (See Japanese page) 
(in English) Solid oxide fuel cell (SOFC) is an efficient generator and researched for practical use. However, one of the problems is the durability. In this study, we research the mechanical correlations among components of SOFC by analyzing the co-occurrence of acoustic emission (AE) events which are caused by damage. Then we propose a novel method for mining patterns from the numerical data like AE. The proposed method extracts patterns of two clusters considering co-occurrence between clusters and similarity within each cluster. We applied the proposed method to AE data, and acquired novel knowledge about damage mechanism of SOFC from the results.
