A solid oxide fuel cell (SOFC) with a liquid antimony anode (LAA) is a potential energy conversion technology for the use of impurity-containing fuels. Atmospheric plasma spraying (APS) technology has become a promising LAA-SOFC preparation method because of its economy and convenience. In this paper, button SOFCs with different cathode materials and ratios of pore former were prepared by the APS method and were operated at 750 °C. The effect of the cathode structure on the electrochemical performance of the LAA-SOFCs was analyzed, and an optimized spraying method for LAA-SOFCs was developed. A tubular LAA-SOFC was prepared using the APS method based on the optimized spraying method, and a peak power of 2.5 W was reached. The tubular cell was also measured at a constant current of 2 A for 20 h and was fed with a sulfur-containing fuel to demonstrate its impurity resistance and electrode stability.

具有液态锑阳极（LAA）的固体氧化物燃料电池（SOFC）是使用含杂质燃料的潜在能量转换技术。大气等离子喷涂（APS）技术因其经济性和便利性而成为一种很有前途的LAA-SOFC制备方法。本文采用APS方法制备了具有不同正极材料和成孔剂比例的纽扣型SOFC，并在750°C下工作。分析了阴极结构对LAA-SOFCs电化学性能的影响，并开发了一种优化的LAA-SOFCs喷涂方法。在最佳喷涂方法的基础上，采用APS方法制备了管状LAA-SOFC，峰值功率达到2.5W。
