建立了描述金属氢化物电极放电过程的数学模型。该模型用于预测金属氢化物电极的极化行为，该电极可用作不同类型的电化学电池的阳极。在模型中研究的电极是圆柱形的，由球形金属氢化物颗粒组成。该模型考虑了在电解质和金属氢化物粉末中的欧姆损失，氢在金属中的扩散，以及金属氢化物颗粒表面的电荷转移反应。该模型用于分析参数的变化如何影响电极的性能
A mathematical model describing the discharge process of a metal hydride electrode is developed. The model is used to predict the polarization behavior of a metal hydride electrode which can be used as an anode in different types of electrochemical cells. The electrode studied in the model is cylindrical, consisting of spherical metal hydride particles. The model takes into account the ohmic losses in the electrolyte and in the metal hydride powder, the diffusion of hydrogen in metal, and the charge transfer reaction at the surface of metal hydride particles. The model is used to analyze how changes in parameters affect the performance of the electrode
