Digital GDL generators: Motivation and benefits of virtual microstructure simulation
Gas diffusion layer (GDL) generators are becoming increasingly important in the digital domain because they enable fast, flexible, and cost-efficient exploration of fuel-cell and electrolysis designs. Traditionally, developing and optimizing GDL structures requires extensive physical prototyping, complex experiments, and significant material costs.
Digitale GDL-Generatoren hingegen ermöglichen es Ingenieur*innen und Forschenden, realistische Mikrostrukturen virtuell zu simulieren und zu erstellen, sodass Leistung, Haltbarkeit und Fluidtransportverhalten lange vor der Herstellung einer physischen Probe getestet werden können.
This accelerates innovation, supports data-driven optimization, and opens the door to advanced applications such as AI-assisted design and automated material discovery. As digital engineering continues to grow, GDL generators provide a crucial bridge between scientific understanding and practical, scalable fuel-cell technology.
Flexible generation of customized microstructures
The GDL GeoApp provides a highly flexible and efficient way to create digital microstructures tailored to a wide range of design requirements. By dynamically adjusting size, resolution, and key material characteristics, it enables researchers to explore realistic virtual materials at a fraction of the cost and time of physical prototyping.
