If we take a closer look at one of the nine layers under the microscope – the GDL layer – the network-like structure and cavities become visible. This layer is porous. Hydrogen, oxygen and water can flow through it.

This is the GDL layer, transferred into a computer model. Researchers are able to create simulations with the help of models. This simulation shows how and where exactly hydrogen, oxygen and water flow through the layer.
