The coal mainly thermal power generation is the main energy supply method; however, the use of coal resources has the issues of nonrenewability of resources, large emission of carbon dioxide, severe environmental pollution, etc. The solid oxides fuel cell (SOFC) has the advantages of high onetime power generation efficiency, ecofriendly 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.
