ZnO/NiO nanocomposite electrodes have successfully been developed using a cost-effective method, and for the first time used in LT-SOFCs at 300-600 degrees C. They exhibit high conductivity and a dual catalytic functionality in both the cathode and the anode for the electrochemical reduction of O(2) and oxidation of H(2), respectively. An excellent fuel cell performance, e.g. a maximum power density of 1107 W cm(-2), has been shown for a symmetrical fuel cell that contained ZnO/NiO nanocomposite electrodes at 500 degrees C. To our knowledge, to date this is by far the highest power density achieved at this temperature.
