Abstract
Among all types of solid oxide fuel cells, the microtubular design demonstrated increased resistance to thermal cycling and a high power density (from 300 to 1000 W/kg and higher). Currently, one of the basic problems is the choice of a material to be used as the cathode; other problems are associated with the microstructure just within the cathodic layer of the microtubular solid-oxide fuel cells. This work is aimed at the studying of the power characteristics of microtubular solid-oxide fuel cells using Ba0.5Sr0.5Co0.75Fe0.2Mo0.05O3 – δ as a cathode material. A cathodic layer with a thickness of 65 µm, including 4 cathodic functional layers and 4 cathodic collecting ones, is optimal and allows reaching the power of a single microtubular solid-oxide fuel cell as high as 750–850 mW/cm2.
