摘      要：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 Ce_(0.9)Sm_(0.2)O_(1.95)(SDC)and perovskite Ba_(0.5)Sr_(0.5)Co_(0.75)Fe_(0.2)Mo_(0.05)O_(3-δ)(BSCFM5),which has a high exchange rate with *** widely used cathode material La_(0.6)Sr_(0.4)Co_(0.2)Fe_(0.8)O_(3-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/cm^(2)at 850℃ was achieved using the proposed two-layer cathode.
