Abstract
The typical MCFC (molten carbonate fuel cell) anode is made of Ni-10%Cr alloy. The work of this paper is focused concerning long life of anode because Ni-10% Cr anode is suffering from sintering and creep behavior during cell operation. Therefore, Ni-coated Alumina powder(20mm) was developed by electroless nickel plating. Optimum condition of electroless nickel coation on 20mm alumina is as follows: pH 11.7, temperature 65~80oC, powder amount 100 dm2/l. The deposition rate for Ni-electroless plating was as a function of temperature and activation energy was evaluated by Arrhenius Equation thereby activation energy calculated slope of experimental data as 117.6 kJ/mol, frequency factor(A) was 6.28018hr-1, respectively.
