A porous NI-AI alloy anode for the molten carbonate fuel cell has been developed to enhance the creep resistance of the anode as well as to minimize the electrolyte loss. A dual-porosity filmed agglomerate model for the Ni-Al alloy anode has been investigated to predict the cell performance. The major physicochemical phenomena bring modeled include mass transfer, ohmic losses and reaction kinetics at the electrode-electrolyte interface. The pre dieted polarization curves are compared with the experimental results obtained from a half cell test. The model predicted very well the steady-state cell performance at the given conditions that characterize the state of the electrode.
