Progress in the Development of Materials of Solid Oxide Fuel Cells

固体氧化物燃料电池(SOFC)低温化进程的推进有利于加快SOFC商品化的步伐,而工作温度的降低势必增大电解质材料的欧姆电阻和电极材料的极化阻抗,为电解质材料和电极材料的开发带来了不小的挑战。从电化学性能及相关使用性能需求出发,简要综述了电解质材料、阳极材料和阴极材料的研究进展,指出了这些材料发展遇到的主要技术问题,并针对这些问题给出了可供考虑的改进方案和思路,对电池材料的性能优化和新型电池材料的设计提出展望。

A decrease in operation temperature could accelerate the commercialization of solid oxide fuel cell(SOFC)technology.However,Ohmic impedance of electrolyte and polarization of electrode sharply increase,as the operation temperature is reduced.Therefore,development of these two components is a challenge for SOFCs.From the perspective of electrochemical properties and so on,this paper is aimed to briefly review the progress in electrolyte,anode and cathode.The main technical problems in materials development will be discussed,while suggestions and ideas to improve their performances will also be proposed.Finally,performance optimization of SOFC materials and the design of novel SOFCs are prospected.
