在800℃的SOFC工作温度下，对Crofer22APU/玻璃陶瓷/阳极负载电解质（ASE）加入样品在空气中进行热循环和热老化测试。对Crofer22APU进行抛光处理，并在900℃下预氧化2小时。研究了两个界面的扩散行为，发现铬和锰从Crofer22APU扩散到玻璃陶瓷中。在Crofer22APU/玻璃-陶瓷界面以及玻璃-陶瓷与YSZ之间没有观察到相互作用、破坏或裂纹形成。
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 °C. The Crofer22APU had been polished and preoxidised at 900 °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.
