A lot of research is going on in the field of glass science to commercialize solid oxide fuel cells (SOFCs). Still, it is a big challenge to develop appropriate glass sealants for a longer duration and sustaining in the operating conditions of this power source. Mixed alkaline earth metal oxides containing silicate or borosilicate glasses could be most suitable as a rigid glass sealant in SOFCs in comparison with borate-and phosphate-based glass sealants. In this review article, the need for the sealants in the planar design of SOFCs, the effect of different modifiers, and intermediate oxides on sealing properties of glasses and glassceramics, particularly, silicate-and borosilicate-based glass sealants have been reviewed. Interaction study of glass sealants with common electrolytes and interconnect materials is also overviewed in this article. In addition to these, future perspectives and suggestions for suitable seal development are also proposed. Novelty statementThis review article is related to the glass sealants for a highly efficient and environment friendly solid oxide fuel cell energy conversion device. Still, it is a big challenge to develop an appropriate sealant to commercialize this energy device. This article provides the researchers with not only progress and latest development in the field of glass sealants but also suggestion and future prospects to develop the sealants.

“…Many works on the sealing materials have been performed in static state in literature. 20,21,[36][37][38] Therefore, the test scenarios in preset work are chosen to be at 800 C for 500 hours to accelerate the evolution of glass-ceramics as well as the glass-metal interface, which provides useful information on the long stability of sealing glasses. This will need a much longer time if testing at a low temperature (e.g., 700 C).…”

“…[15][16][17] Interactions between glass-ceramic sealants and ferritic interconnects at the SOFC operational temperatures have been found to result in the formation of interfacial phases potentially detrimental to the performance of the SOFC stacks. [18][19][20][21] Alkali ions or residual water in some glass compositions signicantly increase the vaporization of chromium from the interconnects. 18,22 The transport of Cr-vapors, as CrO 3 or CrO 2 (OH) 2 , can lead to the formation of alkaline earth chromates on glass surfaces well-removed from the glass-metal interface.…”

“…The study and then the use of commercial FSSs as base material for IC in IT-SOFCs stacks is not a novelty, as it is represented by the case of FSSs AISI 441 and AISI 444 [37][38][39][40][41][42]. Since the manufacture of MIC represents about 45% of the overall stack production costs, the use of this group of FSSs can guarantee a reduction of those costs, even when further actions, e.g., the application of protective coatings, are needed [43].…”

Two commercial ferritic stainless steels (FSSs), referred to as Steel A and Steel B, designed for specific high-temperature applications, were tested in static air for 2000 h at 750 °C to evaluate their potential as base materials for interconnects (ICs) in Intermediate Temperature Solid Oxide Fuel Cell stacks (IT-SOFCs). Their oxidation behavior was studied through weight gain and Area Specific Resistance (ASR) measurements. Additionally, the oxide scales developed on their surfaces were characterized by X-Ray Diffraction (XRD), Micro-Raman Spectroscopy (μ-RS), Scanning Electron Microscopy, and Energy Dispersive X-Ray Fluorescence Spectroscopy (SEM-EDS). The evolution of oxide composition, structure, and electrical conductivity in response to aging was determined. Comparing the results with those on AISI 441 FSS, steels A and B showed a comparable weight gain but higher ASR values that are required by the application. According to the authors, Steel A and B compositions need an adjustment (i.e., a plain substitution of the elements which form insulant oxides or a marginal modification in their content) to form a thermally grown oxide (TGO) with the acceptable ASR level.
