Abstract
Atmospheric plasma spraying (APS) is an attractive method for metal-supported solid oxide fuel cells (MS-SOFCs). In this study, NiO-Gd0.2Ce0.8O1.9 anodes are fabricated by APS. Different spraying distances of 80-120 mm are adopted to investigate the effect on the microstructures and properties of anode coatings. The temperature, velocity and deposition morphology of the anode particles indicate that at a suitable spray distance of 100 mm, the anode particles are fully melted and accelerated under the plasma jet to form an optimal anode coating on the substrate. As a result, the full cell based on the 100-mm anode coating shows a maximum output power density of 940.45 mW/cm2 and an open-circuit voltage of 1 V at 800 °C. The polarization resistance of the cell is 0.234 Ω·cm2. It demonstrates that controlling the APS spraying distance can effectively adjust the anode deposition state and obtain high-performance MS-SOFCs.
