Solid oxide fuel cells (SOFCs) have received widespread attention as an emerging green energy source.Electrolytes,as key materials,directly affect battery performance.Several common electrolyte materials of SOFCs were introduced,and analyzed their advantages and disadvantages.The development trend of SOFCs was low temperature,which can not only reduce the cost,but also improved the long-term operation stability of the battery.Perovskite material was expected to become the preferred material for low temperature SOFCs due to its unique advantages.
