采用机械熔合干法对直径≤53μm的雾化银球包覆1μm厚的（La0.6Sr0.4）0.98Co0.2Fe0.8O3−δ。在700°C下，该材料成功地用作阳极负载的YSZ电解质上的SOFC阴极，在0.7V下产生>500mWcm - 2，并且在>2000h的工作时间内表现出相对稳定的性能（在0.7V下每1000h功率下降约3%）。
Atomized silver spheres (≤53μm diameter) were coated with a 1μm thick layer of (La0.6Sr0.4)0.98Co0.2Fe0.8O3−δvia a mechanofusion dry processing method. The material was successfully utilized as an SOFC cathode on anode-supported YSZ electrolytes at 700°C, producing >500mWcm−2(at 0.7V) and exhibiting relatively stable performance (∼3% power degradation per 1000h at 0.7V) during >2000h of operation.
