Through the exhaustive discharge, the equilibrium state can be reached inside the homogeneous cells and constant residual potential were measured . This study is concentrated on hydrogen-hytrogen ion electrochemical equilibrium on different surface conditions of substrate metals. Large residual potentials were found for the homogeneous cells consisting of reversible hydrogen electrode and irreversible hydrogen electrode. Although the nonzero residual potentials can be explained by adsorption or electric double layer effect, the question whether the non-zero residual potential can be justified in terms of the principles of thermodynamics remains open.金屬氫-氫離子電化學平衡電極表面
