Comparative evaluation of technologies and characteristics of porous conducting composites used in hydrogen fuel cells

The existing technologies for industrially manufactured GDL and their decomposition to the level of the individual constituents were analyzed and systematized. The cost and output of products manufactured with these technologies were compared. It was shown that the technology for manufacturing carbon-polymer paper using fluoropolymers simultaneously as binder and water repellent and the technology for a sheet in the form of a nonwoven has the lowest cost and highest output. If the existing technologies are brought to the large-scale industrial level, GDL made from TEG can be of minimal cost.
