分析了LaNi5储氢过程的热力学平衡关系,根据平衡状态下的热力学函数,导出了能够完整描述整个实验范围P-C-T关系的平衡公式.利用P-C-T平衡公式对不同温度下平衡压力与储氢量的变化曲线进行了拟合分析,计算并讨论了储氢过程中平衡反应的热力学函数.
Based on the thermodynamic functions under equilibrium conditions, the equilibrium equation describing the PCT relationship of the whole experimental range is derived. The curves of equilibrium pressure and hydrogen storage capacity at different temperatures are obtained by using the PCT equilibrium formula Fitting analysis was carried out to calculate and discuss the thermodynamic function of equilibrium reaction during hydrogen storage.
