<P>PROBLEM TO BE SOLVED: To disclose a gas diffusion layer 3 for a fuel cell, which inhibits an electrolyte membrane 1 from being damaged during pressing, while simultaneously maintaining high gas diffusion properties; and to disclose a membrane-electrode assembly 9 and a fuel cell (A) having the gas diffusion layer 3. <P>SOLUTION: The gas diffusion layer 3 for the fuel cell is composed of a first particle material 4 being high-hardness carbon particles, and a second particle material 5 obtained by performing granulation from a mixture of carbon particles (a) and a resin (b). The first particle material 4 contributes to ensure the porosity, while the second particle material 5 contributes to stress dispersion in the horizontal direction by deformation of the second particle material itself. <P>COPYRIGHT: (C)2010,JPO&INPIT |
