“…Conversely, the planar type, despite the inconvenience of the sealing, displays excellent characteristics in terms of the efficiency of the cell (3). In addition, research and development of a planar plate type ceramic fuel cell with a size of approximately 10 cm × 10 cm has been carried out (6)(7)(8)(9) with the aim of achieving commercial viability.…”

The leakage of gas in a planar solid oxide fuel cell (SOFC) stack is one of the important factors associated with stack degradation. When the fuel leaks to the air electrode, the catalytic property of the cathode deteriorates. Further, when air leaks to the anode comprised of Ni metal, the electrolyte thin film is peeled from the anode surface as result of the re-oxidation of Ni. Therefore, one of the ways to prevent these deterioration characteristics of the SOFC stack is to design a sealing method that can prevent gas leakage. In this study, we have developed a stack with specially designed channels which incorporates sealing gaskets that release leaked gas to outside, thereby preventing it from flowing into the fuel and air electrodes and ensuring the stability of the SOFC stack. The stack is designed to function with 10×10 cm 2 size cells, and to undergo frequent thermal cycles rising from room temperature to operation temperature and then back to room temperature.

“…This coupled with the mismatch in coefficients of thermal expansion of different SOFC components makes stress analysis an interesting avenue to explore. Recently, few studies have been performed [32][33][34][35][36][37][38] to analyze stress components inside different components of SOFC. Lin et al [32] analyzed effects of clamping load on the thermal stress distribution in a planar SOFC.…”

“…Five different compressible loads were applied to investigate effects on stress distribution. Gulfam et al [35] analyzed thermal stress inside PEN region of SOFC for co-flow, counter-flow and cross-flow configurations using commercial software, ABAQUS [39]. Maximum stress inside anode layer was found at high-temperature regions located on the anode-electrolyte interface for all configurations.…”
