A simulation of electrochemical kinetics for gas-liquid-solid phase of MCFC anode

A porous NI-AI alloy anode for the molten carbonate fuel cell has been deve loped to enhance the creep resistance of the anode as well as to minimize t he electrolyte loss. A dual-porosity filmed agglomerate model for the Ni-Al alloy anode has been investigated to predict the cell performance. The maj or physicochemical phenomena bring modeled include mass transfer, ohmic los ses and reaction kinetics at the electrode-electrolyte interface. The pre d ieted polarization curves are compared with the experimental results obtain ed from a half cell test. The model predicted very well the steady-state ce ll performance at the given conditions that characterize the state of the e lectrode.
