Molten Carbonate fuel cell (MCFCs) are being applied in commercial power devices due to their high electrical efficiency and fuel flexibility. The anode material in MCFC should have high melting temperature, excellent oxidation resistance, good creep resistance and a good fracture toughness to be successfully used in such environments. In this work, nano zirconia particles were added to Ni-Al anode electrode and their effects on sintering and microstructure were investigated by comparing it with ZrO2-free anode electrode. Results show that zirconia particles can effectively interact with cubic structure of Ni-Al alloys by strengthening the main slip planes thus reducing creep strain. Therefore, this study presents the possibility that nano zirconia can be added to anode for MCFC applications.
