熔融碳酸盐燃料电池ZnO/NiO阴极稳定性及电化学性能研究
, PP. 181-189
Keywords: 熔融碳酸盐燃料电池,NiO,阴极,ZnO,溶解度,EIS
Abstract:
以ZnO作添加物,采用流延成型法制备了ZnO/Ni复合阴极,研究其微观形貌和相组成,并应用交流阻抗谱研究了ZnO/NiO复合阴极在(Li0.62K0.38)2CO3低共熔盐中的稳定性和电化学性能.结果表明,ZnO/Ni复合阴极和Ni阴极具有基本相近的表面形貌、空隙率和孔径尺寸.ZnO的添加能显著降低NiO在熔盐中的溶解度,其中,2mol%ZnO/NiO复合阴极的NiO溶解度比纯NiO阴极的约低1个数量级,并具有较低的电荷传递电阻(接近于纯NiO值),可望成为MCFC一种很有前景的阴极材料.
