对称结构固体氧化物燃料电池研究进展

Progress of Symmetrical Solid Oxide Fuel Cell

当采用碳氢化合物作为燃料时,具有同种电极材料的对称固体氧化物燃料电池(Symmetric Solid Oxide Fuel Cell,SSOFC)通过阴极和阳极的周期性转换,提高了阳极的抗焦化和抗硫中毒能力。通过对近几年来对称电极的分类和整理,总结了已有对称电极的优缺点。综合分析表明,发现适用于除了La_(0.8)Sr_(0.2)Ga_(0.8)Mg_(0.2)O_(3-δ)(LSGM)电解质的单相稳定氧化物对称电极或者开发出新的对称电极材料是必要的。

The Symmetric Solid Oxide Fuel Cell(SSOFC)with identical electrode materials improves the resistance to coking and sulfur poisoning of the anode by periodic switching of the cathode and anode.The advantages and disadvantages of the available symmetrical electrodes are summed up by classifying and collating the symmetrical electrodes in recent years.A comprehensive analysis shows that it is necessary to discover single-phase stable oxide symmetrical electrodes applicable to electrolytes other than La_(0.8)Sr_(0.2)Ga_(0.8)Mg_(0.2)O_(3-δ)(LSGM)or to develop new symmetrical electrode materials.
