Whether battery or fuel cell for the energy transition, electrochemical power storage and converters are indispensable. A real race has broken out around the development of ever better cells, devices and technologies. If you want to be at the forefront here, you need efficient tools.
Accumulators are an established method for temporarily storing energy that can be called up at another time if required. But fuel cells, which convert energy in the form of hydrogen into electrical energy, are also making a comeback. Closely related to the fuel cells are the electrolysers, essentially fuel cells with the opposite sign, which offer a compact method for producing just that hydrogen. What all three devices have in common is that they are based on electrochemistry and electrochemical kinetics on electrode surfaces. However, other properties of these systems, such as transport processes, thermal management requirements, or structural integrity are very different.
Multiphysics simulation can be used for the development of efficient batteries and new fuel cell technologies. In conjunction with experimentation, modeling is capable of optimizing processes and devices faster, more efficiently and more precisely than experimental methods or prototype testing alone. Electrochemical systems in particular are difficult to analyze purely experimentally. Validated models provide insights into the physical and chemical processes that can only be measured imprecisely or not at all. The prerequisite for this is that the models can include multiphysics effects - i.e. the interactions with flow, structural mechanics, thermal or any other physical processes.
COMSOL Multiphysics® is general-purpose simulation software used in all fields of engineering, manufacturing, and scientific research. With the Battery Design Module and the Fuel Cell & Electrolyzer Module, COMSOL offers two dedicated add-on products for the simulation of electrochemical energy storage and converters in research and development, as well as the possibility to extend complex simulation models to easy-to-use simulation apps, which used in all departments of a company.
At the COMSOL Day: Batteries & Fuel Cells everything revolves around the modeling of functional rechargeable batteries, fuel cells and electrolysers in keynote and specialist lectures, a panel discussion and software demonstrations. You can also get answers to your specific questions via direct contact with application engineers. Some of the sessions will cover the features and modules available in COMSOL Multiphysics® for modeling these systems, while others will delve deeper into the underlying physics that must be considered when modeling such systems.
