Metal (NiFe)-supported solid oxide fuel cells were prepared using the cost-effective tape casting, multilayer co-firing, and impregnation methods in this paper. MSC with Ni-YSZ as the functional anode, YSZ as the electrolyte and impregnated La_0.6Sr_0.4Co_0.2Fe_0.8O_3-δ (LSCF) as the cathode. The maximum power density reached 0.72 mW/cm² at 750 °C and the polarization resistance was 0.20 Ω cm². The complex electrochemical processes of MSC was studied by using the distribution of relaxation times (DRT) method and different physical and chemistry processes of MSC were clearly distinguished. Combined the results of DRT and SEM, the coarsening and growth of LSCF and Ni in the electrodes resulted in the degradation of MSC stability. On the whole, the new structure Ni-Fe|Ni-YSZ|YSZ|YSZ-LSCF showing promising prospects for performance improvement and potential applications.

本文采用经济高效的流延流延，多层共烧和浸渍方法制备了金属（Ni Fe）负载的固体氧化物燃料电池。以Ni-YSZ为功能阳极，YSZ为电解质，并浸渍La _0.6 Sr _0.4 Co _0.2 Fe _0.8 O3 _-δ（LSCF）阴极的MSC 。750°C时，最大功率密度达到0.72 mW / cm ²，极化电阻为0.20Ωcm ²。利用弛豫时间分布（DRT）方法研究了MSC的复杂电化学过程，清楚地区分了MSC的不同物理化学过程。结合DRT和SEM结果，电极中LSCF和Ni的粗化和生长导致MSC稳定性下降。总体而言，新的结构Ni-Fe | Ni-YSZ | YSZ | YSZ-LSCF在性能改进和潜在应用方面显示出令人鼓舞的前景。
