Abstract
A porous Ni-Al 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 being modeled include mass transfer ohmic losses and reaction kinetics at the electrode-electrolyte interface The predicted 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
