A porous transport layer, sometimes referred to as gas diffusion layer (GDL) or current collector, has multiple functionalities that influence performance and durability of the electrochemical device. When it comes to electrolysis, the process of splitting water into hydrogen and oxygen using an electrical current, it's important to have an effective gas diffusion layer. This is a layer that helps to evenly distribute the gases produced during electrolysis and enables the efficient operation of the electrolyzer. The gas diffusion layer is typically made of a porous material, such as carbon paper or metal net. This material allows the gases produced during electrolysis to pass through and be distributed evenly. The gas diffusion layer is placed on top of the electrolyte, which is a substance that conducts electricity and enables the electrolysis reaction to occur.
