Abstract
A particularly inexpensive, light, homogeneous and porous gas diffusion electrode (1, 1') for polymer electrolyte membrane fuel cells is produced as follows:
carbonised carbon fibre nonwoven fabric (3, 3') is coated with a mixture of a soot suspension and a polytetrafluoroethylene suspension and then baked. The gas diffusion electrode can be provided with a catalytically active layer (4, 4').
