文摘
- •
La2NiO4+δ (LNO) and La0.6Sr0.4Co0.2Fe0.8O3−δ (LSCF) electrodes are compared.
- •
Both LNO and LSCF are proper air electrodes at intermediate temperature (∼650 °C).
- •
In fuel cell mode, LSCF shows better performance than LNO.
- •
However, in electrolysis mode, LNO is better than LSCF.
- •
LNO is a promising alternative anode for solid oxide electrolysis cells.
