Abstract

A simple fracture testing method, which was combined with acoustic-emission(AE) monitoring, was developed in order to investigate the mechanical performance of solid oxide fuel cells (SOFCs) under simulated environments. The fracture testing method was applied to ceria electrolyte-supported single cells. The fracture damage process was shown to involve vertical cracking and delamination in the cathode, and vertical cracking in the electrolyte. The fracture damages were most likely due to the chemical expansion induced stresses. It was demonstrated that the AE method enabled the detection of the fracture process and determine the condition for the onset of the fracture damage in the single cell.
