双金属耐磨复合管氧还原活性提高，阴极活性和单电池的功率密度输出也有一定程度的提高。600℃时获得了859mWcm-2的最大功率密度。使用修饰后电极的单电池在5h的恒外阻放电过程中保持稳定。氧化铈-碳酸盐中的本征O2-和外源H+不同的离子传导特性导致不同的离子极化过程
The oxygen reduction activity of the bimetal wear-resistant composite tube was improved, and the cathode activity and the power density output of the single cell were also improved to a certain extent. The maximum power density of 859 mWcm-2 was obtained at 600 C. The single cell with modified electrode remained stable during constant external resistance discharge for 5 hours. Different ionic conduction characteristics of intrinsic O 2-and exogenous H+ in cerium oxide-carbonate lead to different ionic polarization processes
