摘　　要：采用丙烯酰胺作为水系凝胶注模法的单体,制备了锥管串接式阳极支撑固体氧化物燃料电池。凝胶注模法制备锥管式多孔阳极(NiO-YSZ)生坯时,反应温度为90℃,无须引发剂和催化剂;随后,将生坯在1200℃下预烧。电解质(YSZ)薄膜采用浸渍法制备在上述阳极多孔支撑体上,在1400℃下共烧结。阴极(Ag-GDC)采用涂刷法涂覆在电解质膜上,并于850℃烧结。制备的单节电池在800℃的峰值功率密度为693 mW·cm^(-2);两节串联电池的开路电压达2.06 V,输出功率达2.31 W(有效面积为4.1 cm^(2))。Tubular cone-shaped anode-supported segmented-in-series solid oxide fuel cells are prepared by using a water-based gel-casting technique with acrylamide as the monomer.In preparing the green body of the porous cone-shaped anode(NiO-YSZ)support,by using the gel-casting technique,the reaction temperature is set at 90°C,without the requirement of initiator and catalyst.Then,the green anode is prefired at 1200°C.An electrolyte(YSZ)film is coated on outside of the anode support by using dip-coating technique and the bilayer is co-sintered at 1400℃.A cathode(Ag-GDC)is applied on the electrolyte by using brush-painting,which is then sintered at 850℃.The as-prepared tubular anode-supported cell gives a peak power density of 693 mW·cm^(−2) at 800℃.The segmented-in-series two-cell-stack shows an open circuit voltage of 2.06 V and a peak power of 2.31 W at 800℃with an area of 4.1 cm2.
