摘要:
A particularly inexpensive, lightweight, homogeneous and porous gas diffusion electrode for polymer electrolyte membrane fuel cells is made in that carbonized carbon fiber nonwoven fabric is coated with a mixture of a soot suspension and a polytetrafluoroethylene suspension and sintered thereafter. The gas diffusion electrode may have a catalytically active layer applied thereto.
