Some discussions on the Warburg impedance (element) would be welcome. For example, if we substitute with an ideal capacitor, we get a semicircle. The Warburg impedance can be modelled using conventional R,C,L but it is always difficult to get a good model for a real electrochemical electrode.chami 15:05, 12 August 2011 (UTC)
