Abstract
This invention relates to electrode substrates for electrochemical cells, particularly low-temperature fuel cells, and processes for their production. Graphitized fiber web structures are used that have a preferred non-planar fiber alignment resulting in high through-plane conductivity. These structures are further impregnated and processed to adjust the final product properties.
