In batteries, electrolyzers, and fuel cells, graphite foil is primarily used for Bipolar Plates (BPPs) and Gas/Liquid Sealing. Foil can be laminated onto cheaper substrates (like plastic or metal) to create a plate that is highly conductive and corrosion-resistant. It acts as the barrier that separates the fuel/electrolyte of one cell from the next. Since it is highly conductive in-plane (along the surface), which make it to be used to pull electrons out of the 3D felt and move them to the external circuit. Unlike felt, which is open and airy, foil is made by compressing expanded graphite flakes into a solid sheet without binders. This is why the graphite foil as the layer behind the felt to prevent the liquid from touching your metal end-plates and to ensure a good electrical path.
