“…For large area cells, this step is a time-consuming process and will inevitably introduce a lot of defects. Recently, atmospheric plasma spraying (APS) is considered as a cost-effective way to produce solid oxide fuel cell components [136][137][138]. Different from vacuum plasm spray (VPS) process, APS is a coating process under normal pressure conditions.…”

“…During this process, the ceramic thermal barrier coating is sprayed on the substrate by means of a robot-assisted plasma gun, which traverses repeatedly above the substrates at a specific speed. The main advantage of porous metallic supported thin coating cell fabricated by APS is to allow enlarging the cell area without sintering defect and improve its mechanical properties [137]. In addition, APS easily controls the component composition and microstructure through variation of spray parameters.…”

This paper reports the results of the thermal stability study of M-YSZ (M= Ni, Cu, Co, Cu-Co, Ni-Cu-Co) SOFC anode cermets materials at different heat treatment temperatures. The cermets were elaborated by atmospheric plasma spraying (APS) with optimised conditions and then submitted to heat treatments at 800°C and 1000°C, respectively. Scanning electron microscopy and X-ray diffraction were used to characterise, respectively, the morphology and structure of obtained films, before and after thermal annealing. A correlation was made between the differential scanning calorimetry analysis results and those obtained by X-ray diffraction. Focusing, in this study, on YSZ matrix thermal stability, the obtained results were as following: the A c c e p t e d m a n u s c r i p t 2 monometallic cermets with the lowest amount of metal and the trimetallic one, exhibited a good stability at 800°C whereas at 1000°C, all considered cermets, were unstable with an eutectoid decomposition of YSZ matrix.

“…High temperature sintering processes can also induce reactions between function layers, such as reaction between LSGM electrolyte and Ni in the anode, but plasma spraying process is a fast sintering process, interaction between electrode interface can be reduced [8,9]. The main advantage of porous metallic supported thin-coating cell fabricated by APS is to allow enlarging the cell area without sintering defects and improve its mechanical properties [10]. In addition to high material deposition rates, plasma spraying processes can easily control the component composition and microstructure through variation of spray parameters, hence, plasma spraying process has thus appeared as a promising candidate for inexpensive and fast cell production, and attracted much attention [9,11].…”
