摘要
采用大气等离子喷涂技术,以活性炭粉作为成孔材料,获得了薄且多孔的中温固体氧化物燃料电池SOFC阳极层。实验研究分析了添加炭粉造孔剂和改进喷涂工艺参数对阳极层孔隙率的影响。结果表明:在合适的喷涂工艺条件下,添加质量比为15%的炭粉并进行后处理可得到孔隙率30.2%的阳极层,满足SOFC对阳极层孔隙率的要求。
Air plasma spray technique was used to gain a thin and porous anode layer ot intermediate temperature solid oxide fuel cell SOFC by taking charcoal active powder as pore-forming agent in this paper. The influence of added charcoal pore-forming agent and improved plasma spraying parameters on porosity of the anode layer were investigated experimentally. The result shows that the anode layer with porosity of 30.2% can be obtained under the C ： YSZ mass ratio of 3 ： 17, suitable spraying parameters and post treatment, and the porosity meets the requirement in the manufacturing of anode of solid oxide fuel cell.
