Description
Summary:The joint strength between a newly developed glass-ceramic sealant and metallic interconnect for application in planar solid oxide fuel cells (pSOFCs) was investigated. A methodology of evaluating the joint strength at room temperature (RT) and 800 oC was developed in testing two types of sandwich-like specimens under shear and tensile loading. Effects of number of sealant-spreading side and aging treatment on the joint strength at RT and 800 oC were studied. Regardless of the testing temperature and loading mode, the joint strength of specimens with two sides of glass-ceramic sealant was greater than that of single-side ones due to a better wetting effect. An aging treatment at 800 oC for 250 or 500 h degraded the shear joint strength at 800 oC by 17%. A longer aging time of 1000 h further reduced the high-temperature shear joint strength by a slightly additional extent from 17% to 19%.
