摘　　要：固体氧化物燃料电池(SOFC)是未来的清洁能源技术之一,电解质是核心部件。ZrO_(2)基SOFC电解质中含有氧空位是氧离子传导的基础,通过在ZrO_(2)中掺杂低价金属离子能够制造氧空位。综述了不同元素掺杂ZrO_(2)基SOFC电解质电性能的研究进展,按照掺杂元素的多少分为一元、二元及多元掺杂ZrO_(2)电解质三大类,在每一大类下,根据掺杂元素的种类特点进行了细分与论述。归纳了ZrO_(2)电解质的性能和掺杂金属离子的关系,以及不同金属离子掺杂的优缺点,展望了ZrO_(2)基电解质的发展趋势。Solid oxide fuel cell(SOFC)is one of the future clean energy technologies,and electrolyte is a critical component.Oxygen vacancies in ZrO_(2)-based SOFC electrolytes are the foundation of oxygen ion conduction,and they can be created through the doping of low-valent metal ions in ZrO_(2).In this review paper,the recent advancements in ZrO_(2)-based SOFC electrolytes doped with various elements were discussed.The doped elements were categorized based on the amount of doping into unitary,binary,and multi-doped ZrO_(2) electrolytes.Each major category was subdivided and analyzed according to the characteristics and types of doping elements.The interplay between the properties of ZrO_(2) electrolyte and doped metal ions,as well as the advantages and disadvantages of different metal ion doping were also summarized.Finally,the paper outlined the developments trends of ZrO_(2)-based electrolytes.
