    Sainmhíniú Unterschied im Elektrodenpotential zwischen einer strombelasteten und einer gleichen unbelasteten Elektrode, die mit ihrem Elektrolyten im Gleichgewicht steht; meist angegeben in mV. Man unterscheidet folgende Typen der Ueberspannung a) Konzentrationsueberspannung, bedingt durch den bei Strombelastung eintretenden Komzentrationunterschied zwischen der ElektrolytschiCht direkt an der ElektrodenOberflaeche-dem Elektrodenfilm und der Hauptmasse des Elektrolyten b) Widerstandueberspannung, bedingt durch den Widerstand des elektrodenfilms; sie ist im gemessenen Wert der Ueberspannung enthalten c) Aktivierungsueberspannung, bedingt durch Hemmungen in der Elektrodenreaktion. Wenn eine Elektrode bei gegebener Stromdichte Sitz einer bestimmten einfachen Elektrodenreaktion ist, so ist die Ueberspannung dieser Reaktion an dieser Elektrode in einem gegebenen Augenblick gleich der Elektrodenspannung die dieser Reaktion entspricht.

    Sainmhíniú the difference in the electrode potential of an electrode between its equilibrium potential and its operating potential when a current is flowing Tagairt "Corrosion Doctors. Electrochemistry Dictionary, http://corrosion-doctors.org/Dictionary/Dictionary-O.htm [14.10.2013]"
    Nóta "The overpotential represents the extra energy needed (an energy loss that appears as heat) to force the electrode reaction to proceed at a required rate (or its equivalent current density). Consequently, the operating potential of an anode is always more positive than its equilibrium potential, while the operating potential of a cathode is always more negative than its equilibrium potential. The overpotential increases with increasing current density, see Tafel equation. The value of the overpotential also depends on the ""inherent speed"" of the electrode reaction: a slow reaction (with small exchange current density) will require a larger overpotential for a given current density than a fast reaction (with large exchange current density). Also referred to as ""polarization"" of the electrode. See also overvoltage. An electrode reaction always occurs in more than one elementary step, and there is an overpotential associated with each step. Even for the simplest case, the overpotential is the sum of the concentration overpotential and the activation overpotential.In electrochemistry, overvoltage is not a synonym of overpotential, although, unfortunately, the terms ""overvoltage"" and ""overpotential"" are sometimes used interchangeably."
