Sintering aids are often used in the fabrication of proton-conducting oxides to facilitate their application in solid oxide cells, but the detrimental effects of sintering aids on electrochemical performance have been noted in early studies. However, the landscape has changed as some recent studies have suggested that overall electrochemical performance is actually enhanced by using sintering aids, making this an important topic for debate. This mini review presents a discussion of the influence of sintering aids on the electrochemical performance of proton-conducting oxides, considering older studies as well as more recent results. The merits and challenges of sintering-aid-modified proton-conducting oxides are discussed.

烧结助剂通常用于制造质子传导性氧化物，以促进其在固体氧化物电池中的应用，但在早期研究中已注意到烧结助剂对电化学性能的不利影响。然而，情况发生了变化，因为最近的一些研究表明，通过使用烧结助剂实际上可以提高整体电化学性能，这使其成为辩论的重要话题。这篇小型综述介绍了烧结助剂对质子导电氧化物电化学性能的影响，同时考虑了较早的研究以及最新的研究结果。讨论了烧结助剂改性质子导电氧化物的优缺点。
