What is it about?
A multi-oxide material LiNiCuZn-oxide was prepared through a slurry method as an anodefor ceramic nanocomposite fuel cell (CNFC). The CNFCs using this anode material, LSCF as cathode material and a composite electrolyte consisting of CaSm co-doped CeO2and(NaLiK)2CO3produced ~1.03 W/cm2at 550C due to efficient reaction kinetics at the electrodes and high ionic transport in the nanocomposite electrolyte. The electrochemicalimpedance spectroscopy revealed low ionic transport losses (0.238 U cm2) and low polar-ization losses (0.124 U cm2) at the electrodes. The SEM measurements revealed the porousmicrostructures of the composite materials at electrode and the dense mixture of CaSm co-doped CeO2and (NaLiK)2CO3. The Brunauer-Emmett-Teller (BET) analysis revealed highsurface areas, 4.1 m2/g and 3.8 m2/g, of the anode and cathode respectively. This study provides a promising material for high performance CNFCs
