• A single layer SOFC is fabricated based on La2NiO4-SDC-(Li0.67Na0.33)2CO3 composite.
• The single cell fed with H2 shows the highest output of 340 mW cm−2 at 700 °C.
• The maximum power density of the cell fed with methanol is 331 mW cm−2 at 700 °C.
• The stability of the cell with H2 and methanol as fuels has been examined.
A single layer solid oxide fuel cell composed of La2NiO4 and samarium dope ceria (SDC)-(Li0.67Na0.33)2CO3 is fabricated and characterized. La2NiO4 shows a K2NiF4 structure in an oxidizing atmosphere, and is decomposed to Ni and La2O3 in a reducing atmosphere at the operating temperature of the cell. The electrical conductivity of the composite material increases with the increase of the content of La2NiO4. At 700 °C, the single cell composed of 30 wt.% La2NiO4 and 70 wt.% SDC-(Li0.67Na0.33)2CO3 exhibits the highest power output of 340 and 331 mW cm−2 with H2 and methanol as fuels, respectively. The stability of the cell with H2 and methanol as the fuels is investigated.
