The effect of Co addition on the electrochemical performance and structural stability of porous Ni anode for molten carbonate fuel cell(MCFC) was evaluated by the anodic polarization and the sintering test in the simulated MCFC anode condition ($650^{circ}C$, 80% $H_2$+20%$CO_2$). The anode current density ranged from 110mA/$cm^2$ to 144mA/$cm^2$ was obtained at +100mV overpotential by additions of Co up to 10 wt.%. The sintering resistance of Ni-Co anodes was higher than that of the pure Ni anode. The increase of sintering resistance seemed to be to the lower diffusion coefficient of Co than that of Ni.
