Abstract
A carbon paper for fuel cells includes a conductive polymer and a polyol having at least two —OH functional groups, and a method for producing the same. The method for producing the carbon paper for fuel cells provides carbon paper with high electroconductivity even when a heat treatment is carried out at low temperature. In addition, the temperature for heat treatment is reduced significantly as compared to conventional carbon paper, and thus it is possible to reduce the overall cost required for producing carbon paper for fuel cells. Further, the carbon paper for fuel cells obtained by the method has high flexibility with low brittleness.
