A non-isothermal model of a nickel-metal hydride cell

A model for a nickel-metal hydride cell was constructed based on the planar electrode approximation. The mass balances of active species, the kinetics of electrochemical reactions, the ohmic effects of internal resistance, an d the energy balance of the whole cell were considered in the model. An emp irical approach was utilized to account for the hysteresis potential behavi or of the nickel electrode. The model predictions showed favorable agreemen t with the experimental data.
