(MS19) Elastic, electrical, and electrochemical processes and properties in porous media

Oral Presentation

Diffusion media are an integral component in electrochemical systems including fuel cells, water electrolyzers, and unitized reversible fuel cells (URFCs). Diffusion media facilitates efficient transport of reactants and products to and from the catalyst layer, enabling electron conduction, and providing mechanical support and thermal management. Advancing our understanding of the key...

566. Upscaling of lithium-ion battery models: from the pore-scale to the cell-scale through homogenization

(MS19) Elastic, electrical, and electrochemical processes and properties in porous media

Oral Presentation

Lithium-ion batteries (LiBs) are currently the leading energy storage technology for applications ranging from portable devices to aerospace vehicles. They are also expected to play a significant role in net-zero energy buildings, with global battery demand projected to increase by approximately 27% annually until 2030. Their advantages include a high energy-to-weight ratio, low...

467. A Film-Based Methodology for Simulating Electrical Properties in Digital Rock Samples

Mrs João Victor Bernardino Afonso e Silva (Wikki Brasil)

(MS19) Elastic, electrical, and electrochemical processes and properties in porous media

Oral Presentation

The resistivity index (RI) is a crucial parameter for characterizing the electrical properties of geological formations. Accurate measurement of RI is essential for understanding fluid distribution and behavior in porous rocks, with direct implications for applications such as hydrocarbon reservoir evaluation and enhanced oil recovery. These assessments are vital for optimizing resource...

491. Fabrication of electrospun micro porous layers for enhanced green hydrogen production

Sergio Diaz (Los Alamos National Laboratory)

(MS19) Elastic, electrical, and electrochemical processes and properties in porous media

Oral Presentation

Proton exchange membrane water electrolyzers (PEMWEs) face performance limitations due to the poor interfacial contact between the catalyst layer and the porous transport layers (PTLs). This issue reduces catalyst utilization and increases contact resistance, leading to non-uniform exposure to applied voltages or currents. Such non-uniformities not only lower efficiency but also accelerate...
