High performance ceramic nanocomposite fuel cells utilizing LiNiCuZn-oxide anode based on slurry method

A multi-oxide material LiNiCuZn-oxide was prepared through a slurry method as an anode for ceramic nanocomposite fuel cell (CNFC). The CNFCs using this anode material, LSCF as cathode material and a composite electrolyte consisting of CaSm co-doped CeO2 and (NaLiK)(2C)O3 produced similar to 1.03 W/cm(2) at 550 degrees C due to efficient reaction kinetics at the electrodes and high ionic transport in the nanocomposite electrolyte. The electrochemical impedance spectroscopy revealed low ionic transport losses (0.238 Omega cm(2)) and low polarization losses (0.124 Omega cm(2)) at the electrodes. The SEM measurements revealed the porous microstructures of the composite materials at electrode and the dense mixture of CaSm co-doped CeO2 and (NaLiK)(2)CO3. The Brunauer-Emmett-Teller (BET) analysis revealed high surface areas, 4.1 m(2)/g and 3.8 m(2)/g, of the anode and cathode respectively. This study provides a promising material for high performance CNFCs. (C) 2018 The Author(s). Published by Elsevier Ltd on behalf of Hydrogen Energy Publications LLC.
