Method for producing carbon paper for fuel cell gas diffusion layer by addition of conducting polymer and carbon paper for fuel cell gas diffusion layer produced by the method

摘要

Disclosed is a carbon paper for a fuel cell gas diffusion layer. The carbon paper can be produced by baking and calcination at a low temperature. This low-temperature heat treatment can greatly reduce the production cost of the carbon paper. In addition, the carbon paper has superior gas permeability and electrical conductivity despite the greatly reduced production cost. The application of the carbon paper to a gas diffusion layer of a fuel cell contributes to reduced fabrication cost and improved quality of the fuel cell. Also disclosed is a method for producing the carbon paper.
