Electrical behavior in the dynamic state with a large signal

Electrical behavior in the dynamic state with a large signal 

In the extensive discussion above, we have focused on the quasi-static behavior of an electrolyzer. To deal with dynamic behavior, and particularly with a large signal, is a highly ambitious aim. For practicality s sake, we cannot go into detail here. Thus, we invite the reader to refer to [TUR 08] and [RAL 11] for all explanations. 

The activation phenomena are coupled with the electrochemical double layer phenomena, which are comparable to a capacitor in the electrostatic sense of the term. The phenomena of species transport are, by their very nature, dynamic in our approach, they will be assigned a dynamic via pseudo-capacitors. The Ohmic phenomena will be considered to have no perceptible dynamic. 

Coupling of the phenomena of activation and double electrochemical layer 

The electrochemical double layer phenomena manifest themselves at each interface between an electrode and the electrolyte. Around these two interfaces, there is spontaneous accumulation of charges of opposite signs on either side of the interface. It is these phenomena which are exploited and maximized in ultracapacitors.
