Model Electrodes with Nonideal Connectivity in Corrosion Analyses

March 14, 2017

Learn the appropriate boundary conditions for performing a corrosion analysis in which an electrode is connected to an external short circuit.

How to Model Electrochemical Resistance and Capacitance

August 24, 2016

Resistive and capacitive effects are fundamental to the understanding of electrochemical systems. The resistances and capacitances due to mass transfer can be represented through physical equations describing the corresponding fundamental phenomena, like diffusion. Further, when considering the resistive or capacitive behavior of double layers, thin films, and reaction kinetics, such effects can be treated simply through physical conditions relating electrochemical currents and voltages. Lastly, resistances and capacitances from external loading circuits can easily be represented in the COMSOL Multiphysics® software.
