A novel family of perovskites, SrNb 0.1 Co 0.9−x Fe x O 3−δ (SNCF, 0.1 ≤ x ≤ 0.5), shows not only high oxygen reduction reaction (ORR) activity at operating temperatures below 600 °C ( e.g. peak power density of 1587 mW cm ⁻² at 600 °C) but also low thermal expansion coefficients (TECs) and improved CO ₂ resistivity.
