Solid oxide fuel cell (SOFC) stacks are extremely vulnerable to mechanical failures in any of their constituents, which ultimately lead to cell cracking. Like all devices, distinct failure sequences arise from different events or design particularities. The understanding of the interactions between the different components is crucial to effectively mitigate their possible adverse effects. This study comprises two papers, which aim at compiling data on the mechanical properties of the materials used in intermediate-temperature, anode-supported SOFC stacks, in the view of stress analysis. Part I focuses on the ceramic cell materials. This Part II covers the metallic interconnects, the glass-ceramic sealants or compressive gaskets and gas-diffusion layers. A selection is performed among the possible solutions found in stack designs, depending on the availability of the data. The reported properties of the materials, namely thermal expansion, strength, elastic or elasto-plastic and creep behaviour, are discussed in terms of modelling frameworks.
