The present invention discloses a cathode electrocatalyst for a solid oxide fuel cell, a preparation method thereof, and an application thereof. Among them, the material of the cathode electrocatalyst for the solid oxide fuel cell is BCFZY-GDC-PrO x , where BCFZY is BaCo 0.4 Fe 0.4 Zr 0.1 Y 0.1 O 3‑δ , GDC is Ce 0.8 Gd 0.2 O 1.9 . The present invention mainly improves the catalytic activity of the cathode by improving the material of the cathode electrocatalyst for the solid oxide fuel cell, thereby improving the power density of the SOFC. Specifically, the present invention impregnates PrO x nanoparticles into the BCFZY-GDC composite cathode coating, thereby improving the oxygen ion exchange performance of the composite cathode during the ORR (oxidation-reduction) process, and the impregnation of PrO x can also greatly improve the power density of the single cell.
