| 摘 要： | 讨论了直流法在线测量钯氢化物电极电阻时的电化学效应，计算了电解液的共导、测量电流与电解电流引起的浓差电池效应以及电极作为集流体引起的电阻贡献。结果表明：当电极具有高的长度与半径比值、粗糙的表面、高的溶液电导以及大的电解电流时容易引起显著的附加电阻。

| Abstract: | Additional resistances contributed to that of Pd|H electrode caused by the co-conduction of electrolyte, the concentration-cell effect, and collection of electrolysis current in the in-situ resistance measurement using the direct current were calculated. It is found that an electrode with a large ratio of length to radius, the active surface, the surrounding electrolyte with high conductance and high electrolysis current induce prominent additional resistances. |
