摘要：

Thermal cycling and thermal ageing tests were performed on Crofer22APU/glass-ceramic/Anode-Supported-Electrolyte (ASE) joined samples in air at the SOFC operating temperature of 800 degrees C. The Crofer22APU had been polished and preoxidised at 900 degrees C for 2 h. The diffusion behaviour at the two interfaces was examined and revealed slight diffusion of chromium and manganese from Crofer22APU into the glass-ceramic. No interactions, failure or crack formation were observed at the Crofer22APU/glass-ceramic interface and between the glass-ceramic and YSZ. Copyright (C) 2011, Hydrogen Energy Publications, LLC.
