摘要：

We develop a mathematical model for analyzing the discharge performance of a thick porous metal-hydride electrode. A numerical solution method together with partial analytic solutions is presented. The potential loss in the electrode is divided into parts corresponding to the different loss mechanisms, and an averaging method is used for an easy interpretation. The model is applied to simulate a continuous discharge, an interrupted discharge, and the effect of varying the values of certain parameters.
