The stabilized cathodes were fabricated by coated Ni powder which was synthesized by hydrothermal treatment in . The morphology of coating was characterized by spectroscopic techniques to investigate the optimal synthesis conditions such as temperature, reaction time, and reactant molarity. coating was consisted of , , and , and the amount of was increased with increasing time and molarity of . The mechanical properties of the stabilized cathodes were also measured to evaluate the stability in molten carbonate fuel cell (MCFC) applications. The bending strength of the stabilized cathode was significantly improved compared to the typical cathode. The pores of the stabilized cathode showed typical bimodal distribution in size due to the micropores developed by coated materials, and the overall porosity was higher than 75% under optimal synthesis conditions, which is also promising for MCFC applications.
