Outline of Final Research Achievements	The degradation of the cathode electrode catalyst by the start up and shut down process is one of pressing problems in polymer electrolyte fuel cell. The catalyst degradation is spread in the whole space with patches. However the cause and mechanism of this degradation don't become clear in detail. In this research, the catalyst degradation depends on the start up and shut down process was analyzed under the in-situ (operand) three dimensional space, use XCT-XAFS (X-ray computerized tomograph X-ray absorption fine structure).
