摘要

在这项研究中，我们开发了具有两层阴极的微管固体氧化物燃料电池（MT-SOFC）：与缓冲层（BL）相邻的复合阴极功能层（CFL）和阴极集流层（CCCL）。CFL 由缓冲层材料 Ce0.9Sm0.2O1.95 (SDC) 和过氧化物 Ba0.5Sr0.5Co0.75Fe0.2Mo0.05O3-δ (BSCFM5) 的混合物组成，后者与氧气的交换率很高。CCCL 采用了广泛使用的高导电性阴极材料 La0.6Sr0.4Co0.2Fe0.8O3-δ (LSCF)。使用所提出的双层阴极，MT-SOFC 在 850 °C 时的峰值功率密度大幅提高到 1.2 W/cm2。

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 Ce_0.9Sm_0.2O_1.95 (SDC) and perovskite Ba_0.5Sr_0.5Co_0.75Fe_0.2Mo_0.05O_3-δ (BSCFM5), which has a high exchange rate with oxygen. The widely used cathode material La_0.6Sr_0.4Co_0.2Fe_0.8O_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/cm² at 850 °C was achieved using the proposed two-layer cathode.
