COMSOL Day: Batteries & Fuel Cells

Modeling batteries, fuel cells, and electrolyzers for transport mobility

Battery, fuel cell, and electrolyzer development has been an integral part of the electric vehicle and power industries, particularly as the investment in eco-friendly technologies has increased. The COMSOL Multiphysics® software is a multiphysics simulation platform that helps you set up physics-based, high-fidelity models of electrochemical cells, including material transport, charge transport, heat transfer, fluid flow, and electrochemical reactions. You can also incorporate lumped models into system models and digital twins, such as electric vehicle drivetrains, and create simulation apps for use by nonexperts.

Join us for COMSOL Day: Batteries & Fuel Cells to learn from keynote talks, technical presentations, and a panel discussion about the benefits of using multiphysics simulation to study and design batteries, fuel cells, and electrolyzers. We will also give an overview of the relevant features in COMSOL Multiphysics® and demonstrate how the software can be used across large development teams.

Tech Lunches are informal sessions where you can interact with COMSOL staff and other attendees. You will be able to discuss any modeling-related topic that you like and have the opportunity to ask COMSOL technology product managers and applications engineers your questions. Join us!

1:30 p.m.

Thermal management is an important aspect across different automotive applications. Within vehicle electrification, thermal management is crucial. Batteries, fuel cells, and many other components produce or require heat as they work best within narrow temperature intervals.

In this session, an overview of the features and benefits offered by COMSOL Multiphysics® to model thermal management of systems through convection and conduction will be demonstrated and presented. In particular, a demonstration of forced convective cooling will be shown.

Parallel Session
Introducing the Battery Design Module

The Battery Design Module is an add-on product to COMSOL Multiphysics® that includes predefined physics-based interfaces for modeling detailed structures in everything from battery porous electrodes to battery packs themselves. This includes modeling the behavior of a battery: electrode kinetics, electric fields, chemical deposition, ionic migration, heat production, thermal stresses, conjugate heat transfer within the thermal management system, and more.

In this session, we will present the features of the Battery Design Module, demonstrating a few of them.

Introducing the Fuel Cell & Electrolyzer Module

The Fuel Cell & Electrolyzer Module in COMSOL Multiphysics® expands the sphere for modeling electric vehicles and energy conversion. This product can be used for modeling low- and high-temperature hydrogen fuel cells and water electrolyzers based on different electrolyte-types, such as proton exchange membranes, alkaline, molten carbonates, and solid oxides.

In this session, we will present and demonstrate simulations of electrochemical reactions, electrolyte charge transport, gas-phase mass transport, and convective flow, as well as two-phase water/gas transport in both fuel cells and electolyzers.

2:45 p.m.
3:00 p.m.
Parallel Session
Simplified and Lumped Battery Models

The Battery Design Module allows you to create models that can be detailed on the micro level to models with homogenized structures to even simplified lumped models. This module covers all aspects of modeling and designing batteries as it gives you the choice between detailed understanding of the battery to how it operates within the electric vehicle drivetrain.

In this session, we discuss and will demonstrate how lumped models can be used to describe battery packs in electric vehicle systems.

Parameter Estimation for Battery, Fuel Cell, and Electrolyzer Models

Many of the parameters used in electrochemical models may be difficult, if not impossible, to measure or determine explicitly. COMSOL Multiphysics allows you to use physics-based models and transient methods to extract the value of these parameters.

In this session, we will demonstrate how parameter estimation can be used for characterizing battery and fuel cell design, as well as operation.

3:30 p.m.
3:45 p.m.
Parallel Session
Battery Degradation

Battery systems are often burdened by unwanted side reactions at the electrodes. The Battery Design Module can be used to simulate various aging and degradation mechanisms and the resulting capacity fade in batteries.

Any arbitrary by-reaction, such as hydrogen and oxygen evolution, the growth of a solid electrolyte interface due to deposition, metal plating, metal corrosion, and graphite oxidation can be included in a battery model through the flexibility built within the Battery Design Module.

In this session, we will present and demonstrate the capabilities of this module to model degradation in batteries and the process of building and running a capacity fade model.

Two-Phase Flow and Transport Processes in Electrochemical Cells

Two-phase flow is prevalent in many electrochemical systems, such as fuel cells and electrolyzers. The CFD Module together with the Fuel Cell and Electolyzer Module have inbuilt features that can model such phenomena. These can include disperse and surface tracking methods.

This session will focus on the two-phase features of the Fuel Cell & Electrolyzer Module, and how these can be coupled to electrode kinetics and chemical species transport.

4:15 p.m.
