Evaluation of Ni-Ni3Al(5Â wt.%)-Al(3Â wt.%) as an anode electrode for molten carbonate fuel cell. Part II: wetting ability and performance in unit cell operation

In unit cell operation, the electric resistance of Ni-Al(5) and Ni-Ni3Al(5)-Al(3) were relatively lower than those of any other electrodes. After 120 h operation of the unit cell, the cell performance and the endurance of Ni-Ni3Al(5)-Al(3) were even better than those of any other electrodes. And also its thickness shrinkage and porosity changes after unit cell operation were the least in five kinds of electrodes. The performance of Ni-Ni3Al(5)-Al(3) as anode seems to be caused by the synergy effect between the strengthening characteristics of Ni3Al and electric conductivity of Al.
