The study focuses on the role of flow and reactive transport in porous media for various hydrogen applications such as fuel cells, MOFs, nano-carbons, and sub-surface storage. It emphasizes the importance of optimizing porous media for efficient hydrogen flow by considering parameters like reactive surface area and transport properties. These factors are difficult to determine experimentally due to the molecular processes involved, like adsorption, which are sensitive to contamination and inhomogeneity. To address this, the researchers propose utilizing inverse gas chromatography (iGC) to systematically analyze how porous media deviates from its ideal model. This method aims to provide insights into the behavior of porous media for hydrogen applications. The funding support from the Irene-Curie Fellowship and NWO-Veni underscores the significance of this research in advancing our understanding of hydrogen transport in porous materials.
