Abstract

The invention relates to the field of in-situ characterization and particularly relates to an in-situ high-temperature spectrum testing device. The device comprises a shell; a heat insulation layer isarranged in the shell; a heating furnace is arranged in the heat insulation layer; a sample table is arranged in the heating furnace; a placement groove with an upward opening is formed in the sampletable; a sample holder is arranged in the placement groove; a sample cover is arranged above the sample holder; a window is formed in the shell above the sample cover; and external light can enter the sample holder through the window; a cooling system is arranged in the shell; the in-situ high-temperature spectrum testing device further comprises a temperature detection device which can be used for detecting the temperature in the sample holder; the device further comprises a gas path system; the interior and the exterior of the shell are sealed; and the gas path system can introduce gas fromthe lower portion of the sample holder, and the gas can be discharged out of the shell from the upper portion of the sample holder. With the in-situ high-temperature spectrum testing device of the invention adopted, various spectroscopy tests, gas environment and high pressure can be simultaneously considered.

Description

technical field [0001] The invention relates to the field of in-situ characterization, in particular to an in-situ high-temperature spectrum testing device. Background technique [0002] Solid oxide fuel cells (SOFCs) have attracted much attention due to their high conversion efficiency for converting various chemical fuels into electrical energy. However, performance degradation due to carbon deposition (coking) on ​​nickel-based anodes remains a technical challenge. At present, there are mainly two strategies to suppress the coking of nickel-based anodes. One is to add other gases such as steam, CO2 or O2 to hydrocarbon fuels. By adding these gases, the O / C ratio in the fuel increases, leading to a situation where carbon deposition can be thermodynamically avoided. However, adding other gases requires additional energy, reducing overall energy efficiency. The second strategy is to introduce an anode catalyst layer (e.g. RueCeO2 or Cu1.3Mn1.7O4) or to incorporate metals...
