Gas Diffusion Layer - Custom

The Gas Diffusion Layer (GDL) is a very important supporting material in a Membrane Electrode Assembly (MEA). Gas diffusion layers are a porous material composed of a dense array of carbon fibers, which also provides an electrically conductive pathway for current collection. The two types of gas diffusion layers most commonly used are carbon paper and carbon cloth. Both are carbon fiber based porous materials: carbon paper is non-woven, while carbon cloth is woven fabric, thus no binder is needed.
