Wire Electrode

Application ID: 3471


The electrochemical cell shown in this model can be regarded as a unit cell of a larger wire-mesh electrode that is common in many industrial processes. One of the most important aspects in the design of electrochemical cells is the current density distributions in the electrolyte and electrodes. Non-uniform current density distributions can be detrimental for the operation of electrochemical processes. In many cases, the parts of an electrode that are subjected to a high current density can degrade at a faster rate. Knowledge of the current density distribution is necessary to optimize the utilization of the electrocatalysts that are typically comprised of expensive noble metals. Non-uniform deposition and consumption, unnecessarily high overvoltages, energy losses and possible unwanted side-reactions represent effects that should be minimized. This example simulates the primary, secondary, and tertiary current density distributions of an arbitrary electrochemical cell with wire electrodes. The current density distributions are investigated in succession so as to also demonstrate good working practices by gradually introducing complexity when modeling electrochemical cells.

The combination of COMSOL® products required to model your application depends on the physics interfaces that define it. Particular physics interfaces may be common to several products (see the Specification Chart for more details). To determine the right combination of products for your project, you should evaluate all of your needs in light of each product's capabilities, consultation with the COMSOL Sales and Support teams, and the use of an evaluation license.
