overpotential
noun overpotentials
-
The difference between the electric potential of an electrode or cell under the passage of a current and the thermodynamic value of the electrode or cell potential in the absence of electrolysis.
One of the factors that limits their development and use is that known anode and cathode electrocatalysts produce useful current densities only at high overpotentials.
