Performance of Samarium Oxide Doped Cerium Oxide Co-Doped Solid Oxide Fuel Cells with Different Ratios of Silica as Electrolyte

On the basis of previous studies, it can be understood that the method of changing the electrolyte material to achieve the increase of battery power is a very common approach. In this research, the Ce0.8Sm0.2O1.9 (SDC) electrolyte material was synthesized by co-precipitation method, and mixed with silica material in different ratios to prepare a new electrolyte material, which was tested on I-V and I-P curves and simply characterized by SEM. The experimental results indicate that at 550℃, the maximum power was measured to be maintained at about 0.53 W, while it can only reach 0.39 W when 100% SDC is used as the electrolyte material, it can be seen that, the selection of suitable materials for the electrolyte mixing and doping, which can effectively improve the power of the battery.
