直接碳固体氧化物燃料电池(DC-SOFC)作为一种全固态的能量转换装置,可直接将固体碳燃料中的化学能转化为电能,比起其他燃料电池具有更高的电效率和燃料利用率。然而,直接使用碳作为燃料还面临诸多挑战,如碳燃料低的电氧化活性和传质,以及阳极侧三相反应界面有限。其中,电池的阳极反应对电池的电化学性能起到关键性的作用。本文详细介绍了新型钙钛矿材料在直接碳固体氧化物燃料电池阳极上的应用,为未来DC-SOFC阳极材料的设计和研究提供了参考和方向。

Direct carbon solid oxide fuel cell(DC-SOFC)is an all-solid-state energy convertor,which can directly convert the chemical energy stored in solid carbon fuel into electricity,which demonstrates superior electrical efficiency and fuel utilization compared to other types of fuel cells.Nevertheless,using carbon directly as fuels still faces several challenges,like low carbon electrooxidation activity,sluggish mass transfer and limited triple phase boundaries in the anode side.Wherein,the anode reaction plays a vital role in determining the electrochemical performance of the DC-SOFC.In the paper,novel perovs-kite materials towards the application of anodes for DC-SOFC are introduced detailedly.This paper pro-vides an important reference and guidance for the design and investigation of the anode materials for DC-SOFC.
