摘　　要：为了控制薄膜固体氧化物燃料电池阳极的小孔尺寸,该研究提出了一种工艺简便的聚合物注入方法。首先,将液体聚苯乙烯以一定的压力注入到多孔氧化镍-氧化钇稳定的氧化锆(NiO-YSZ)基片;然后,经过机械切割,利用溅射法在阳极基片上沉积300 nm厚的电极薄膜;最后,利用热解法将基片孔隙的聚苯乙烯移除,完成多孔阳极基片上的电极薄膜制备。利用该法获取的NiO-YSZ基片具有更好的小孔尺寸可控性,同时可以实现无支撑薄膜的制备,从而显著提高大面积薄膜固体氧化物燃料电池的生产效率。To control the pore size of anode in thin film solid oxide fuel cells,a simple polymer injection method was introduced to replace conventional anode functional layer method in this paper.Firstly,the liquid polystyrene was pressed and injected to the porous nickel oxide yttria-stabilized zirconia (NiO-YSZ)substrate.Then,a 300-nm-thick film was deposited on a composite substrate by sputtering procedure.Finally, by removing polystyrene from the pore of substrate through pyrolysis,a free-standing thin film on the porous substrate could be obtained.The polymer-injected NiO-YSZ substrate has more controlled pores.Moreover, with the proposed method,throughput of large scale thin film solid oxide fuel cell can be improved.
