Perovskite type fuel cell electrode material, preparation method and application

The invention relates to a perovskite type fuel cell electrode material, a preparation method and application, and belongs to the technical field of fuel cell negative electrode materials. According to the electrode material, Ba with a large atomic radius is used at the A site, meanwhile, different amounts of Sr are doped, the molecular formula is Ba < x > Sr < 1-x > Fe < 0.95-y > Ti < 0.05 + y > O < 3-delta >, and x is 0.25-1; and y is equal to 0.02 to 0.08. Compared with an SFT material in the prior art, the BaFe < 0.9 > Ti < 0.1 > O < 3-delta > material prepared by the preparation method disclosed by the invention shows higher electrochemical performance; meanwhile, Sr is further doped at the A site of the BaFe < 0.9 > Ti < 0.1 > O < 3-delta >, so that the Ba < 0.5 > Sr < 0.5 > Fe < 0.9 > Ti < 0.1 > O < 3-delta > is prepared, and the phase forming stability of the BaFe < 0.9 > Ti < 0.1 > O < 3-delta > material is improved. 本发明涉及钙钛矿型燃料电池电极材料、制备方法及用途，属于燃料电池负极材料技术领域。所述电极材料在A位使用较大的原子半径的Ba，同时掺杂不同量的Sr，分子式为BaxSr1
