異種二相間の内部電位差への挑戦（その1） 序論：なぜ測れないのか

Abstract

Again, the consideration of the electrical potential in the electrolyte, and especially the consideration of the difference of potential in electrolyte and electrode, involves the consideration of quantities of which we have no apparent means of physical measurement, while the difference of potential in “pieces of metal of the same kind attached to the electrodes” is exactly one of the things we can and do measure.
