GIC 2025 - Breakout Session - Hydrogen Energy: Demo: Simulating Rel. Perm. in Compressed FC/E Layers

The material properties of a Porous Transport Layer (PTL) measured on a lab bench are not the properties it has inside an operating fuel cell or electrolyzer. During assembly, the clamping pressure from the bipolar plate fundamentally changes the microstructure. This impacts all key PTL functions: delivering water to the catalyst, removing product gases, and providing a conductive pathway for electrons. So, how can you obtain accurate, in-situ data for your performance models? In this in-depth demonstration from the GeoDict Innovation Conference, Dr. Jürgen Becker, co-founder and Head of Support at Math2Market, walks you through the complete digital workflow. Drawing on 20 years of experience, he shows how to simulate the relative permeability of a PTL as a function of both mechanical compression and fluid saturation—a workflow that was impossible just a few years ago. Follow step-by-step as a realistic digital material is created from scratch and subjected to analysis that mimics real-world operating conditions: 03:50 - Virtual Material Generation: Watch how a realistic, anisotropic model of a sintered titanium fiber PTL is created. 09:13 - Modeling In-Situ Compression: Learn the critical steps to simulate PTL compression, capturing the non-linear stiffening from new fiber contacts. 13:48 - Calculating Transport Properties: See how to compute absolute and relative permeability curves for the various compressed structures. 20:55 - The Final Result: The workflow yields a comprehensive dataset—a family of curves representing permeability as a function of both compression and saturation. 22:16 - Automation is Key: Discover why complex parameter studies like this are best handled by a simple Python macro for consistency and efficiency. This powerful workflow is not limited to permeability; it can be applied to calculate diffusivity and conductivity as well. The ability to characterize materials under realistic, in-situ conditions is a game-changer for designing the next generation of hydrogen technologies.
