Microtubular solid oxide fuel cells with a two-layer LSCF/BSCFM5 cathode
In this study, we present the development of microtubular solid oxide fuel cells (MT-SOFC) with a two-layer cathode: a composite cathode functional layer (CFL) adjacent to the buffer layer (BL) and a cathode current-collecting layer (CCCL). CFL consists of a mixture of BL material Ce0.9Sm0.2O1.95 (SDC) and perovskite Ba0.5Sr0.5Co0.75Fe0.2Mo0.05O3-δ (BSCFM5), which has a high exchange rate with oxygen. The widely used cathode material La0.6Sr0.4Co0.2Fe0.8O3-δ (LSCF) with high electrical conductivity was used as the CCCL. A significant increase in the peak power density of the MT-SOFC to 1.2 W/cm2 at 850 °C was achieved using the proposed two-layer cathode.
