摘要： Disclosed is a process for making a gas diffusion electrode that comprises an electrically conductive substrate, a gas diffusion layer (GDL) and an active layer (AL). The process comprises forming the GDL and/or the AL by pressing and/or rolling a mass obtained by subjecting electrically conductive carbon material and polymeric binder and, in the case of the AL, electroactive catalyst to high energy mixing in a liquid medium, followed by the separation of solid matter from the liquid medium and, optionally, drying of the separated solid matter.
