The Fuel Cell & Electrolyzer Module is an add-on to the COMSOL Multiphysics software for gaining a deeper understanding of fuel cell and electrolyzer systems, which is useful for designing and optimizing the electrochemical cells. The types of systems that may be studied include proton exchange membrane fuel cells (PEMFCs), hydroxide exchange (alkaline) fuel cells (AFCs), molten carbonate fuel cells (MCFCs), and solid oxide fuel cells (SOFCs), as well as the corresponding water electrolyzer systems. However, the module accommodates all types of fuel cells and electrolyzers.

Mathematical models help scientists, developers, and engineers understand processes, phenomena, and designs of reacting systems. The Chemical Reaction Engineering Module, an add-on to the COMSOL Multiphysics® software platform, provides a user interface for creating, inspecting, and editing model equations, kinetic expressions, functions, and variables. After developing a validated model, it can be used for different operating conditions and studies, leading to new ideas as a result of the intuitive understanding of the relation between hypothesis and results. Solving the model equations over and over for different inputs leads to a true understanding of the studied system. Additionally, the Chemical Reaction Engineering Module, along with other tools in COMSOL Multiphysics®, is developed with optimization in mind, providing state-of-the-art mathematical and numerical methods adapted for chemical systems.

Model and Control Electrodeposition Processes with the Electrodeposition Module. Decorative electroplating assuming secondary current distribution with full Butler-Volmer kinetics for both the anode and the cathode. The deposited thickness on the front and the backside of the piece is shown.

Model Electrochemical Corrosion Processes and Cathodic Protection Designs with the Corrosion Module. A steel structure immersed in seawater is protected from corrosion through 40 sacrificial anodes. This example models the potential distribution at the surface of the protected structure assuming a constant limiting current for oxygen reduction at the protected surface.

Analyzing electromagnetic systems and processes that encompass static and low-frequency ranges requires a powerful and flexible simulation tool. The AC/DC Module add-on to the COMSOL Multiphysics® platform provides you with a wide range of modeling features and numerical methods for investigating electromagnetic fields and EMI/EMC by solving Maxwell`s equations. The multiphysics capabilities of the COMSOL® software make it possible to investigate the impact of other physical effects, such as heat transfer, structural mechanics, and acoustics, on an electromagnetics model.

Define and solve models for studying systems containing fluid flow and fluid flow coupled to other physical phenomena with the CFD Module, an add-on product to the COMSOL Multiphysics® simulation platform.

The Optimization Module is an add-on package that you can use in conjunction with any existing COMSOL Multiphysics Product. Once you have created a COMSOL Multiphysics model of your product or process, you always want to improve on your design. This involves four steps. First, you define your objective function – a figure of merit that describes your system. Second, you define a set of design variables – the inputs to the model that you would like to change. Third, you define a set of constraints, bounds on your design variables, or operating conditions that need to be satisfied. Last, you use the Optimization Module to improve your design by changing the design variables, while satisfying your constraints. 

COMSOL Compiler™ helps you share knowledge and expertise in the form of modeling and simulation applications with anyone you want. When you add COMSOL Compiler™ to the COMSOL Multiphysics^® simulation platform, you can convert the applications you build in COMSOL Multiphysics^® into standalone applications with the click of a button. The compiled applications can be run without a COMSOL Multiphysics^® or COMSOL Server™ license, which gives you full control over your simulations, letting you distribute them at your own discretion.

The COMSOL Server™ product helps you spread the benefits of simulation throughout your organization. As the platform for deploying and running applications built by your in-house simulation experts, COMSOL Server™ helps you streamline the R&D workflow, efficiently share knowledge and analyses across departments, and rapidly respond to customers` needs. The web interface for COMSOL Server™ comes with administrative tools for managing access to the applications you have uploaded, user accounts, user groups, and multiprocessor utilization. Administrator-verified end users can upload, access, and run applications housed in the Application Library of COMSOL Server™ through web browsers or a desktop-installed client.
