Method for producing roll-type gas diffusion layer having excellent spreading property

A method for producing a roll-type gas diffusion layer is disclosed. The method includes preparing a carbon paper from carbon fiber chops having a low modulus of 10 to 100 Gpa; impregnating the prepared carbon paper with a phenol resin, and then carbonizing the resin-impregnated carbon paper at 1,80...
