金属/陶瓷密封件的气密性是SOFC堆长期可靠运行的关键要求。对于轻型汽车设备的应用,如辅助动力装置(APU),特别是接头对快速热循环的抵抗力对于满足客户期望和确保APU子系统的寿命至关重要。[1]对已运行的全尺寸SOFC堆和堆组件进行事后分析是开发过程的重要组成部分,从材料选择、[2,3]组件设计和构造,到堆组装和运行。为了更深入地理解全尺寸叠加后测试分析结果,通常有用的是,开发一个基本的损伤机制假设,应用模型系统的复杂性降低。出于这个原因,在现实的热化学环境中的简化试样的热机械测试被认为是一个关键的贡献,以提高从测试后分析到开发周期的反馈。
The gas-tightness of metal/ceramic seals is a key requirement for reliable long-term operation of SOFC stacks. For the application in light-weight automotive devices like auxiliary power units (APU) in particular the resistance of the joints to rapid thermal cycling is of essential importance to meet customer expectations and to ensure longevity of the APU sub-system.[1] Post-mortem analysis of operated full scale SOFC-stacks and stack components is an essential part of the development process, reaching from material selection,[2, 3] component design and construction, to stack assembly and operation. For deeper understanding of full-scale stack posttest analysis results it is often useful to develop a basic damage mechanism hypothesis applying model systems of reduced complexity. For this reason, thermomechanical testing of simplified specimens in realistic thermochemical environment is considered to be a key contribution to boost feedback from post-test analysis into the development cycle.
