  "textContent": "This fuel-cell gas diffusion layer includes a conductive porous layer 21 a constituted by: porous carbon formed so as to have a porosity distribution substantially uniform in a stacking direction with respect to a membrane electrode assembly 10; and a PTFE resin arranged dispersedly across the inside of the carbon. When a ratio of a surface of the carbon to a surface that is exposed without being covered with the PTFE resin is defined as an exposure ratio, the exposure ratio of a surface, on a cathode electrode 12a side, of the conductive porous layer 21 a, is higher than the exposure ratio, on a diffusion-layer base material 22a side, of the conductive porous layer 21 a.",
