Fuel cells, electrolysers, and steam reformers play a crucial role in the production and utilization of hydrogen within the energy sector. However, the complexity of these devices often necessitates costly and time-consuming real-life experimentation, acting as a barrier to the widespread adoption of hydrogen technologies. To address this challenge, design engineers are turning to modelling and simulation techniques to gain a comprehensive understanding of the interactions among various chemical, electrochemical, and transport phenomena affecting these devices. By employing tools like COMSOL, engineers can simulate processes such as electrolysis and steam reforming, while also modeling different types of fuel cells including PEMFCs, AFCs, MCFCs, and SOFCs. Additionally, the simulation can extend to nonstandard cells and electrolysers, incorporating factors like multiphase flows, heat transfer, and thermodynamic properties. This webinar by Ross from COMSOL UK will showcase how a Multiphysics approach is crucial for modeling hydrogen technologies, highlighting the benefits of a digital simulation approach in R&D. Attendees will gain insights into the types of hydrogen technologies that can be modeled and simulated, and how companies are effectively utilizing simulation for advancing their R&D efforts in the hydrogen industry.
