Fabrication and Performance of Atmospheric Plasma Sprayed Solid Oxide Fuel Cells with Liquid Antimony Anodes

Abstract A Solid oxide fuel cell (SOFC) with a liquid antimony anode (LAA) is a potential energy conversion technology for 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 measured 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 by 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 hours and fed with a sulfur-containing fuel to demonstrate its impurity resistance and electrode stability.

Electrolyte layers for solid oxide fuel cells (SOFCs) consisting typically of yttria-stabilized zirconia were prepared using atmospheric plasma spraying in a first step and sintered in a second one. The influence of particle size on sintering kinetics and microstructure development was analyzed by comparison of nanostructured and conventional YSZ layers. Sintering of free-standing coatings differ significantly from that of coatings on substrates.
