Abstract

See full text

A process for modifying a carbonized substrate and a modified carbonized substrate obtained therefrom are provided. The process involves the application of a mixture containing a hydrophobic polymer and a carbonaceous material onto a carbonized substrate which is not subjected to a hydrophobic treatment. The subject invention uses a simpler procedure to modify a carbonized substrate to provide a modified carbonized substrate with good conductivity, air permeability, and hydrophobicity. The modified carbonized substrate is suitable for use as the material for the gas diffusion layer of the electrode in fuel cells.
