Abstract: The anode and the cathode of the thin film solid oxide fuel cells are usually fabricated as the mixed-ionic-electronic-conducting (MIEC) porous electrode in order to increase the triple phase boundaries where the electrochemical reactions occur. In this research, Ni, which is the catalyst of the hydrogen oxidation reaction in the anode, and scandia-stabilized zirconia, which presents a high oxygen ion conductivity, are mixed and finally fabricated as the MIEC anode. Experimental results show that triple phase boundaries can be increased and the polarization resistance can be decreased in comparison with the usage of pure Ni anode. However, the increasing of triple phase boundaries also causes the improvement of ohmic resistance, and the overall performance of fuel cell is still decreased.
