Disclosed is a carbon fiber paper for diffusing solid polyelectrolyte fuel cell gas, having fine pores with an average diameter of 10-20µm formed in the gaps of carbon fibers that constitute the carbon fiber paper, and a plurality of non-penetrating pores with an average diameter of 50-500µm formed in the direction from one surface toward the other. The carbon fiber paper has a thickness of 50-400µm, and the non-penetrating pores of the carbon fiber paper have depths of 20-80% of the carbon fiber paper thickness, and a unit area count of 100-1000 pores/cm2. |
