抄録
The purpose of present research is to estimate the degradation mechanism of solid oxide fuel cell (SOFC) by using combining non-destructive test and electrochemical measurement during loading test Mechanical degradation and chemically degradation were investigated by acoustic emission (AE) measurement system and electrochemical measurement,respectively. In the investigation of fracture process with AE amplitude distributions, high amplitude signal, middle amplitude signal and low amplitude signal correspond to vertical craking, delamination in the cathode, and vertical cracking in the elctrolyte respectively. It was demonstrated that the AE method enabled us to detect the above-mentioned mechanical damage and to determine the condition for the onset of the damage in the single cell.
