Abstract

The invention belongs to the field of solid oxide fuel cells, in particular relates to a solid oxide fuel cell structure and a preparation method thereof. The cell structure comprises a cell cathode layer, an electrolyte layer and a cell anode layer in sequence from top to bottom, wherein the cell cathode layer is divided into a PrBaCo2O5 layer and an LSM (La0.8S0.2MnO3) layer from top to bottom; the electrolyte layer is YSZ (Yttria Stabilized Zirconia); the cell anode layer is Ni-YSZ; and the thickness of the PrBaCo2O5 layer is 2-4 microns. Because PrBaCo2O5 has higher catalytic performance, oxygen diffusion coefficients, surface exchange coefficients and oxygen ion migration capability, the oxygen adsorbing capability and oxygen dissociating capability of a cathode can be improved by adopting a PrBaCo2O5-LSM/YSZ/Ni-YSZ structure and material system; and the solid oxide fuel cell structure has the characteristic of improving the cathode performance of the solid oxide fuel cells.

Description

technical field [0001] The invention belongs to the field of solid oxide fuel cells, in particular to a solid oxide fuel cell structure and a preparation method thereof. Background technique [0002] With the depletion of oil and the serious problem of environmental degradation that people are facing, research and development of new energy conversion technology has become the mainstream idea in today's society. Solid oxide fuel cells are environmentally friendly, high energy conversion efficiency and widely used in fuels.
