A fuel cell generates electrical energy and heat from hydrogen and oxygen – and the only “waste” product is water. The optimal transport of the reaction gases H2 and O2 to the electrodes and the efficient discharge of the reaction products electricity and water can significantly increase the performance levels of polymer-electrolyte membrane fuel cells (PEMFC). The most important component here: The Gas Diffusion Layer (GDL). The carbon fiber nonwoven hicoTEC® NE is perfectly suited for this task.
In detail: The central role of the gas diffusion layer (GDL)
The actual electrolysis reaction takes place between the two electrodes that are integrated in a thin membrane. The reaction gases are added via the bipolar plates and the GDL optimally distributes the gases to the electrode surfaces and discharges the reaction products. Several hundred of these layers are connected into a fuel cell stack to provide sufficient power.
