固/液相等离子喷涂制备固体氧化物燃料电池复合电极
Fabrication for the Composed Electrode of Solid Oxide Fuel Cells by Atmospheric and Suspension Plasma Spray
摘要
Abstract
A method for fabricating composed electrode of solid oxide fuel cell (SOFC) on silicon substrate by atmospheric and suspension plasma spray is presented. Anode and cathode layers were deposited by atmospheric plasma spraying (APS) using dry powder feedstock; Electrolyte layer was deposited by suspension plasma spraying (SPS) using mechanical injection. Suspension penetration within the plasma jet was monitored by a CCD camera and the best injection pressure was 0.25MPa by the characteristics analysis of the CCD pictures. The composed electrode layers were characterized in terms of microstructure and composition by SEM and EDAX. Experimental results showed that spray distance was the most important parameter, which influenced electrolyte microstructure, deposition efficiency and porosity; suspension plasma spray could fabricate thin (25μm), fine grain (2-4μm) and dense (porosity of 2.15 %) electrolyte layer of SOFC.关键词
