Current Density Distribution in a Solid Oxide Fuel Cell
Application ID: 514
This model presents a study of the current density distribution in a solid oxide fuel cell (SOFC).
The model includes the full coupling between the mass balances at the anode and cathode, the momentum balances in the gas channels, the gas flow in the porous electrodes, the balance of the ionic current carried by the oxide ion, and a balance of electronic current. A truly large number of couplings in this multiphysics model.
Results show that as a consequence of oxygen depletion, the current density distribution is poor, with most of the current produced close to the cathode inlet. This means that the cell is not used optimally.
This model example illustrates applications of this type that would nominally be built using the following products:バッテリ＆燃料電池モジュール
however, additional products may be required to completely define and model it. Furthermore, this example may also be defined and modeled using components from the following product combinations:
- COMSOL Multiphysics® and
- either the バッテリ＆燃料電池モジュール, or 化学反応工学モジュール and
- either the バッテリ＆燃料電池モジュール, 腐食解析モジュール, 電気化学モジュール, or 電気めっきモジュール
The combination of COMSOL® products required to model your application depends on several factors and may include boundary conditions, material properties, physics interfaces, and part libraries. Particular functionality may be common to several products. To determine the right combination of products for your modeling needs, review the 製品仕様一覧 and make use of a free evaluation license. The COMSOL Sales and Support teams are available for answering any questions you may have regarding this.
