Abstract: A cathode material comprises bimetal-doped barium cobaltite-based perovskite and a bi-directional protonic ceramic fuel cell comprising the same. In a cathode material according to an embodiment, barium cobaltite is doped with scandium (Sc) and tantalum (Ta), and the cathode material is represented by the following Formula 1:


BaScxTa0.2−xCo0.8O3−δ  [Formula 1]



where X is 0.001
