Modeling Hydrogen Fuel Cells & Electrolyzers

The Fuel Cell & Electrolyzer Module add-on to COMSOL Multiphysics^® features a wide range of functionality for modeling electrochemical cells with porous and solid electrodes, including gas-diffusion electrodes and gas-evolving electrodes. Scientists and engineers in the renewable energy field rely on the module for the study and design of cells, from the unit cell scale to the stack scale.

The module's unique modeling capabilities include descriptions of the transport of neutral and charged species for electrolytes of arbitrary composition, with ready-made formulations for the most common electrolyte types. Electrode kinetics can be described using Butler–Volmer, Tafel, or user-defined expressions of the overpotential and local electrolyte concentration. Multiphysics couplings allow for simulation that combines species transport with fluid flow, including, e.g., multiphase flow for gas-evolving electrodes.

In this webinar, you will get an overview of the modeling and simulation capabilities of the Fuel Cell & Electrolyzer Module and learn how it can be used in research and development in the field.
