【摘要】 综述了铈基氧化物在固体氧化物燃料电池(SOFCs)中应用的研究进展。基于SOFCs中的不同组件,铈基氧化物在SOFCs中的应用主要分为如下三个部分:铈基氧化物在电解质、阴极、阳极中的应用。通过不同元素的掺杂,铈基氧化物可以具有较高的离子电导率,作为电解质可以减少电池的欧姆电阻,同时也可以提高阴极的催化活性,以及改善阴极与电解质之间的界面性能,此外,还可以应用于阳极之中,能够改善阳极的抗积碳和抗硫中毒性能。为提高SOFCs中低温性能以及改善抗积碳、抗硫中毒性能提供了新的思路。更多还原

【Abstract】 This paper reviewed recent advancement on applications of ceria-based oxides in solid oxide fuel cells( SOFCs). The applications were divided into three main categories based on different components of the SOFCs: electrolyte,cathode and anode. Higher ionic conductivity could be achieved for ceria-based oxides by doping with different elements and the ohmic resistances of SOFCs could be reduced,the catalytic activity and the cathode/electrolyte interface could be improved when the ceria-based material applied in cathode,in addition,ceria-based material could improve the ability of anti-carbon deposition and anti-sulfur poison used in anode. It provides a new avenue for increasing the performances at reduced or intermediate temperatures,and improving the ability of anti-carbon deposition and anti-sulfur poison for SOFCs.更多还原
