A method for making a cathode material for a solid oxide fuel cell, comprising steps of:
- a) processing a first mixture which includes gadolinium oxide, cobalt oxide, and an alkali metal precursor containing an alkali metal to obtain a perovskite type complex oxide represented by Formula 1:
- Gd1-xMxCoO3-δ Formula 1
- wherein
- M represents an alkali metal,
- x is larger than 0 and not more than 0.75, and
- δ ranges from 0 to 2;
- b) grinding the perovskite type complex oxide into a powder;
- c) mixing the powder and a binder to obtain a second mixture;
- d) processing the second mixture to obtain a green compact;
- and
- e) sintering the green compact to obtain the cathode material.
