基于钪资源的固体氧化物燃料电池产业发展现状及建议

Development status and suggestions of solid oxide fuel cell industry based on Sc resources

当前,我国以煤炭为主的火力发电为主要的能源供应方式,但煤炭资源使用存在资源不可再生、二氧化碳排放量大、环境污染严重等问题。固体氧化物燃料电池(SOFC)具有一次发电效率高、产物环境友好等优点,被公认为21世纪的革命性绿色能源技术之一。本文围绕SOFC系统未来主要发展方向,对SOFC系统中氧化锆基、氧化铈基、钙钛矿基电解质材料性能进行综述,指出基于钪资源的氧化锆基电解质材料是当下电解质材料产业化的优选路径。我国钪资源储量优势明显,钪资源供给能够保障燃料电池新能源产业链持续安全发展,因此,建议从国家层面加强资源供给链、制造产业加工链、产品应用链和回收链各环节的政策引导,做好顶层设计,加速钪基SOFC产业孕育,牢牢把握新一代能源产业变革浪潮。

The coal mainly thermal power generation is the main energy supply method;however,the use of coal resources has the issues of non-renewability of resources,large emission of carbon dioxide,severe environmental pollution,etc.The solid oxides fuel cell(SOFC)has the advantages of high one-time power generation efficiency,eco-friendly products and so on,which is recognized as one of the revolutionary green energy technologies in the 21st century.In this paper,review is made around the aspects of future development direction of SOFC system,the performance of the zirconium oxide based,cerium oxide based and perovskite based electrolyte material in the SOFC system,which points out that the scandium resource based zirconium oxide electrolyte material is the current optimal route for industrial production of electrolyte material.China has obvious advantage in scandium resource reserves,the supply of scandium resource can ensure the sustainable and safe development of the fuel cell new energy industrial chain,therefore,it is suggested that efforts be made in the national level to strengthen the policy guidance to all links of the resource supply chain,processing chain of manufacture industry,product application chain and recycling chain,and to make good top tier design to speed up the fostering of SOFC industry and firmly grasp the wave of the new generation of industrial energy transformation.
