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.

Climate change and air pollution have increased the need for automotive electrification, thus large resources have been invested in the development of new battery and fuel cell technologies. While batteries seem to be the main candidate for powering cars, fuel cells may be a necessity for trucks and heavier transport, in which they can provide a higher energy density. COMSOL Multiphysics® offers large advantages in the development in this field by providing users with the tools needed to better understand the physics of fuel cell designs. It also enhances fuel cell development through its ability to optimize designs and their operating conditions.
The combination of the Battery Design Module, the Fuel Cell & Electrolyzer Module, and equation-based modeling has made COMSOL® one of the leading platforms for modeling and simulation in the field. With the Application Builder, simulation apps, and the Model Manager, our users have been able to take a major step forward by enabling a larger community of scientists and engineers to benefit from high-fidelity simulation.
Join us in this session to learn more about how simulation apps and the Model Manager can be used to facilitate collaboration between teams and to spread the benefits of multiphysics simulations in organizations.
Mathematical Modeling of SEI Growth
In a lithium-ion battery cell, the solid electrolyte interphase (SEI) is known to grow on the surface of a graphite anode during various cell conditions: trickle charge, open circuit, and cycling. In this keynote talk, Ralph White will discuss mathematical modeling of the SEI, reviewing a misconception in the literature as well as the soundness of existing models used for analyzing cells under various conditions. He will touch upon cathodic protection in the process. He will then compare the use of a kinetic model from the literature to an alternative diffusion model for predicting the growth of the SEI layer under trickle charge conditions and explain how a combination of the kinetic and diffusion models can be used to improve upon the predictions of the kinetic or diffusion model alone. Finally, he will explain how this combined approach can be applied under the open circuit and cycling conditions of the cell.
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.
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.
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!
Numerical Simulation of the Primary Alkaline Zn–MnO2 Battery Discharge Process
In this presentation, Xiaotong Chadderdon will introduce a continuum model developed in the COMSOL® software to simulate the discharge behavior of primary Zn–MnO2 alkaline batteries. Both macroscopic and microscopic phenomena are integrated to describe the species diffusion in cell-length and particle-length scales. The predicted battery performance is validated against experiments under different rates of continuous and intermittent discharge. The model is applied to better understand the evolution of internal gradients and local conditions, polarization sources and sensitivity to design parameters. Accurate point prediction is challenging for small design changes due to the complexities in reaction chemistries and limitations imposed by model assumptions; however, predictive modeling is shown to be useful for larger design and experimental changes.
Bio-Inspired Inverse Design Enables Innovation in Hydrogen Fuel Cell Flow Field Plates
In 2014, Toyota launched the world’s first mass-produced, commercially available hydrogen fuel cell vehicle, the Mirai, powered by the Toyota Fuel Cell System (TFCS). Since then, the TFCS has been further utilized in various applications including heavy-duty trucks, buses, forklifts, boats, and stationary power generation. This keynote talk discusses the latest technical innovation of fuel cell flow field plates. An inverse design and dehomogenization framework has been developed to discover innovative flow channel designs with improved multiphysics performance. The framework uses a homogenization-based inverse design to optimize the orientation distribution of the anisotropic porous media flow. It exploits bio-inspired Turing-pattern dehomogenization to generate microchannels. The optimized flow channel designs exhibit similar geometric patterns to those observed in naturally occurring systems (e.g., lungs, leaves, and blood vessels) while outperforming conventional parallel and serpentine benchmark designs.
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.
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.
