Hydrogen overvoltage may be defined as the difference of potential that. exists between a reversible hydrogen electrode, and an electrode, in the same. solution, at which hydrogen, H2, is being formed from hydrogen ions. A. reversible hydrogen electrode is one at which the reaction.
So, what is the meaning of over voltage?
Definition of overvoltage. 1 : the excess potential required for the discharge of an ion at an electrode over and above the equilibrium potential of the electrode. 2 : voltage in excess of the normal operating voltage of a device or circuit.
